I am pondering a GTX 260 card with GDDR3 memory and a GTX 275 card with DDR 3 memory? Both are 896 cards. Which would be the better card for the i7-920 w/V8 cooler overclocked to 3.66 coupled with the Asus P6T mobo? Looking for 1920x1200 res from a 23" Samsung monitor. 1st person shooter games are the gaming target with some spreadsheet work using Office software. OS will be Vista 64 bit premium.
