I was wondering wether i should buy the 768mb version or the 1gb versions. From what i read a lot of people say to stay away from the 768mb version but the prices are vastly different. Right now on newegg i can get 2x gtx 460 768mb for ~260 (130 a peice after MiR) or the 1gb versions for 400. This is a difference of $140. I will be playing on a dell u2311h 1080p monitor doing mostly video editing and gaming, i have a phenom 2 x4 955 oc and 4gb memory.
the GTX 460 768mb SLI is plenty for 1080p. here is a review of the evga OC GTX 460 768mb but all the cards OC well even with MSI afterburner.
just add another to your system if your motherboard supports SLI. Once you do that you have darn near twice the performance of one GeForce GTX 460 768MB graphics card and it gives you performance that rivals the GeForce GTX 480 and Radeon HD 5970 video cards. The performance numbers on the EVGA GeForce GTX 460 768MB SuperClocked SLI setup were impressive and an SLI setup will cost you less than a GeForce GTX 480
True. I don't think if going with SLI, $140 more is justified for 1GB's. Also, 768mb models are as good overclockers as 1GB's. Though a few games would keep on coming requiring 1GB for smooth gameplay at full hd at max settings, I don't think you'd mind that if you care for 140 dollars.
