Best CPU motherboard combo in 2025 – top AMD and Intel picks for any budget

A good CPU is only as good as the motherboard that it sits in, which is why it’s important to choose the best CPU and motherboard combo for your PC. With the constant one-upmanship of the world of CPUs, things change rapidly, luckily, we’re at a stable point right now where the majority of mainstream CPUs can sit on one best motherboard, depending on whether it’s AMD or Intel.

The Ryzen 9000 series has changed the game, while mostly showing that efficiency is not the be-all-and-end-all, the launch was rocky, to say the least. It may be wise to hold off on 9000 series CPUs for now, until the release of AMD’s 800 series motherboards. However, the 9000 series will work just fine on any 700 series AM5 motherboard you might currently have. With all that being said, how do we pick the best combinations?

The Core i9-14900K and the ASUS Z790 Dark Hero make a fantastic CPU and motherboard combo thanks to the plethora of features that the Z790 offers. Not to mention the fact that the 14900K is still top of the pack (for now) when it comes to single-core performance. So if you want to game on the Intel platform, the 14900K might be the best choice for you. Intel has patched the issues that caused chip degradation with the 14th and 13th-generation CPUs, so it’s safe to buy again.

This Intel CPU is still using the split core technology introduced in the 12th generation Alder Lake CPUs, this means that you get 24 cores and 32 threads. 8 of those cores being hyperthreaded P-Cores, and 16 E-Cores, with half of those E-Cores also being hyperthreaded. As we mentioned in our review of the 14900K. That’s how it’s able to score so damn high in the multi-core tests. It just packs more cores than any other CPU on the market right now, mainstream anyway. And with Single-core boost speeds topping 6GHz, it’s easy to see why it performs so well when gaming.

The Dark Hero is built for enthusiasts who want the best of the best out of their motherboard, as we mentioned in our review, with a robust 20+1 teamed power solution delivering clean and stable power when the 14900K needs it the most. Power delivery is one of the motherboard’s most important functions, as it facilitates power to all components within the PC. When overclocking it’s important to have the most stable power possible, as any fluctuations could knock the CPU out of whack. And as it turns out, the 14900K is quite the beast when properly overclocked.

AMD’s Ryzen 9000 series may be a little held back by the level of efficiency that AMD is trying to achieve, but there is a light at the end of the tunnel, and that light is named the 9950X. In our review, we state that this CPU is highly capable of being AMD’s latest flagship and rips through tasks when you enable PBO. This is why we think it will make a fantastic pair with the X670E Hero, as it has a robust power delivery system to give the CPU a constant stream of stable power.

The 9950X has 16 fully hyperthreaded cores totalling 32 logical processors. This suggests that it would be good at multi-core workloads, and good it is. In our testing, the 9950X smashed the 40k mark in Cinebench, which isn’t something we see a lot of that’s for sure. With that in mind, the Ryzen 9 is let down a little by its single-core performance. If you’re looking for a CPU that will do tremendously well when gaming, you might be better off waiting until X3D launches.

The X670E Hero is one of the best X670 motherboards around, it’ll also likely be cheaper around the launch of the 800 series motherboards. The 18+2 Phase power delivery system makes it great at delivering power when it is needed. If you have a soft spot for PCIe Gen 5 storage, this motherboard will fill your needs, with two dedicated Gen 5 M.2 slots. Not to mention the fact this motherboard comes coupled with a PCIe Gen 5 card. If you’re interested, we suggest you read more about this motherboard in the review we posted.

7800X3D + MSI B650M Project Zero

Specifications

• Motherboard RAM Capacity : 128GB DDR5 @ 7600+(OC)
• CPU Boost Speed : up to 5 GHz
• Motherboard PCIe Version : PCIe Gen 4 Storage + GPU

What We Think

A very good pair for a sleeker, smaller gaming rig. You don’t need a whole lot of overclocking capabilities with the 7800X3D, as the 3D V-cache cannot handle it.

Reasons to Buy

• Good value for money
• Looks good, really like the white
• Thermal armour keeps VRMs cool

Reasons to Avoid

• Slight performance loss vs X670E
• Difficult to install if your case doesn’t accommodate for the rear connections
• Micro-ATX, so only 1 PCIe slot

• Shop on Amazon

This is a more budget pairing based on gaming performance. The 7800X3D is very capable of pushing frames in even the most intense of games, the 3D V-cache gives it a nice boost where it lacks in raw power from its inclusion on the chip. Because of the V-cache, and the limitations it poses, we have paired this CPU with a B650M, because you just don’t need that much power with an X3D CPU. This way, you can save some money and perhaps upgrade your GPU instead.

X3D shines in gaming scenarios, as we found out when we reviewed the X3D. If you’re looking for something similar but for productivity, then the base 7700X might be of interest to you. There is no 7800X as of yet, but if the random reignition of AM4 has taught us anything, the lack of base 7800X may not last forever.

The B650M Project Zero is based around power delivery and aesthetics, boasting a 3-layered power delivery system of 10+2+1 power phases, it’s puts even the best motherboards to bed. This would be a build centered around looks, or at least aesthetically focused. That is where Project Zero shines, all of the connections on the motherboard are at the rear, meaning there are no wires visible on the front. When we reviewed this motherboard, we thought that this was a nice touch from MSI.

• CPU Boost Speed : up to 4.5 GHz
• Motherboard PCIe Version : PCIe Gen 4 storage + GPU

What We Think

The 5800X3D is still one of the best value gaming CPUs on the market, paired with the X570 Aorus Pro, it makes for a fantastic budget gaming combo.

Reasons to Buy

• Cheap enough on sale
• Amazing Zen 3 performance
• Efficient

Reasons to Avoid

• Sometimes rare to find new
• Revisions can cause confusion with BIOS update
• Old platform, can invest in newer technology for similar money

• Shop on Amazon

The Ryzen 7 5800X3D is to this day probably one of the best value gaming CPUs on the market, it’s on the AM4 platform, which is technically still in support, but it can’t be for much longer. This is quite literally one of the only downsides that this CPU has, apart from the limitations, if you’re on a budget and want to game, this CPU is a fantastic choice, as we stated in our review. However, I wouldn’t pick this up for multitasking workloads, as the first version of the 3D cache limited the CPU quite heavily.

The 3D V-cache in the 5800X3D is limiting because it’s not a fan of high voltages or temperatures, so AMD has limited the boost clock speeds and the overclocking capabilities of this CPU quite massively. Because of this, it’s not the best at performing multi-core workloads. But its gaming performance is phenomenal compared to the other CPUs of the time. It took until the 9700X for a base AMD CPU to beat it in gaming performance.

The X570 Aorus Pro that we have chosen to pair this AM4 CPU with is more than capable of supporting it. The 5800X3D doesn’t need much power thanks the the limitations on overclocking that it has, but this motherboard is packed with features such as PCIe Gen 4 connectivity on the GPU and the storage, which should keep you going for a while. As we mentioned in our review, if you want something aesthetically pleasing and very capable, then this might be the motherboard for you.

How to choose the best CPU and Motherboard combo

When looking to create your own CPU and motherboard combo, there are a few things that you should be on the lookout for. If you make a mistake here, you could cause yourself a massive headache, or worse, lose money. So we suggest following this guide closely if you’re looking for something different but don’t know how to pull it off. We got you.

Compatibility

Intel and AMD motherboards are different, and it’s been that way for a long long time. But it’s also important to remember that motherboards can change on the same brand by generation, so we created a little table to help out with socket selection in case you are ever stuck on what motherboard works with what CPU.

We didn’t list them all, just the up-to-date ones. If we wanted to list all of the CPUs, we’d be here forever.

Power consumption

CPUs are the second major consumers of power in the PC, with the first being the best GPUs, with that being said, you still need to watch what you’re putting in your PC if you care about a high energy bill at the end of the month. It would help if you also made sure that the motherboard and the PSU can handle all of the power that the CPU is requesting. More on that in a minute.

Budget

There’s no point shopping for motherboards that you can’t afford, or that take up way too much room in your budget, while it is true that motherboards are one of the most important components in your system, you’re paying for features mostly, not necessarily functionality. CPUs and GPUs cost way more because they are the main drivers of performance, given that the motherboard mainly provides power, you should opt for a board that can fully support the other hardware you are choosing and one that suits your connectivity needs.

Power delivery

On that, power is the most important thing a motherboard does, and some are better at it than others. If you have a high-end CPU that you plan on overclocking, then you will want a motherboard with a higher power phase count and a more robust delivery system. That way you can overclock your CPU without having to bother too much about stability within your system. Usually, the most premium motherboard chipsets (X670, Z790, X570) etc, have the best power delivery systems available to them.

Size

Despite what people tell you, size does matter, well, for PC building anyway. Larger motherboards require a larger case and tend to be more feature-rich and include more connectivity. By contrast, smaller motherboards tend to have fewer features but are more budget-friendly as a result.
