Budget Gaming PC Pc vs Pc

[flashgordon]

So I think I've made a decent low budget PC! Just asking do you all think It's worth it?

Current PC
Dual Core AMD X2 3800+ 2.0ghz I hate this thing, so old I feel im missing out.
2 gigs of RAM I think DDR2 500, pretty old, but DDR2
x1950pro 512mb It's nice, I guess :)
ummmm 300wat power supply, but I have a thermal take Video card power supply, so don't worry about my power supply!
That's about all you need to know!

Now I'm asking should I just buy a Ati 4850? Or should I upgrade too a whole new build encluding.

What are you trying to do- game? What is your budget? Yes that new setup would hand it to your old one. but we can help you better tweak it if we know what you are trying for.

Well yes if you guys could tweak it up for me, under 600, with the best possible proframnce for games! I just built one on newegg for 609. If you guys can try to build one, I'll compare it thanks guys :)

Yes I want to game with it, and other stuff of course.
