HL2
Doom 3
I just ordered an Athlon 64 3000+ and a DFI LANParty N4 Ultra which will be OC'd. I'm keeping my old video card (Nvidia 5900SE) until I can safely afford a 6600GT but even with my old setup (Athlon XP 2500+) HL2 ran ok...little choppy but ok.
Gonna benchmark it when the new parts come in, then again when the new video card comes in. Not expecting anything spectacular, but I just want a solid rig.
