I have this config:
ASUS P5KE- WIFI
SEAGATE BARRACUDA 500GB 16MB
OCZ VINDICATOR CPU COOLER
OCZ 4GB REAPER DDR2 800 4-4-4-15
OCZ 8800GTX @612/1080(=8800ULTRA)
OCZ PROXSTREAM 1000WAT
THERMALTAKE ARMOR CASE
LG M228WA MONITOR with 1680x1050 resolution
XP 32 + SP3 RC1
I can play every game out there maxed out with no problems (including Crysis @ 1680x1050 with 0xAA and everything @ ultra quality_with
TRIPLE C hack_)and i am really happy with its performance.
Of course there are better cards out there,but my card is still plenty fast and i dont really want to upgrade.
I dont recommend u upgrading either because for 1280x1024 the 8800GTX is more than enough
