Well you guys were right! I went out and got a 550watt power supply and plugged her in and it worked perfect. Night and day difference. GRID is amazing. Every game i run maxed out now. 1240x1024 4XAA 16AF. worth every penny. Got it running at 750mhz and 1000mhz (4000mhz) memory. Didn't bother really ocing the core as it can't be oc'd that much and there isn't really a point right now, because without a doubt my athlon 64 3200+ is sort of a bottleneck. Mind you I have it oc'd to Athlon 64 4200+ speeds. I'm impressed with the dramatic jump in performance. GRID is fluid, WOW is amazing with everything turned up. BF2 is amazing now and Crysis is stunning and fluid maxed out.
