Buying advice XPS 630 vs XPS 720

[trigger753]

I'm trying to decide which way to go XPS 630 or XPS 720. My budget is around 2500.00 (U.S.) I will put a second hard drive in myself.
Any and all advice or comments are welcome.
One more thing I have bought a CyberPower PC before. Never again. I have been happy with the XPS line in the past and there is no way to convince the wife to let me buy a boutique computer again.
Thanks. Trigger
