EVGA GTX 460 1024mb SLI'd with older 768MB model. Will it work?

[descartes2140]

I currently am running an old system with one EVGA GTX 460 768MB. Going to be upgrading to Ivy Bridge soon, and thought a nice cheap upgrade for the system would just be to SLI another EVGA GTX 460. However, they seem to be out of stock of my old 768mb brand. Will the newer 1024mb one's work?

I read somewhere that the Memory Interface should match up. Is that the case?

Thanks guys. First post and all, hope it's in the right section and all the jazz.

You are in the correct section and no it won't work because the 768MB card has a 192 bit MI and the 1GB card has a 256MB MI.

Is MI the same as Bus Width? Cause the EVGA GeForce GTX 460 823MHZ 1024MB I am looking to get has 192 bit of that. Would that work?

what's your resolution./what DX/.............. regardless, I would never buy a second low end card. if I couldn't afford a better single card that could perform twice or more what sli-ing would ( hypothetically ) I would hold off until i could buy one and run the old one into the dirt.

I play games at 1920 x 1080. My native resolution for my monitor. I just thought it might be a decent upgrade. Seems like two 460 would be better than a 560.

If the most I could a afford was another 460 or one 560. Should I just wait?

Its a V2 card but I don't know if it would SLi with your current one.

 

[swifty_morgan]

perhaps you misunderstood me. No, I wouldn't buy a second card. I would buy a single card that would be as good as - or better than - what you theoretically would get by sli-ing those 460's.

 

[descartes2140]

Yes, but I don't want to spend that much. So that means waiting essentially.

ever hear the phrase "shooting yourself in the foot" ?
