sorry i was reading around and didnt really find a whole lot of info on what i was needing to know.. so anyway i was wondering if u can run sli without matching cards? i have a xfx 7900gs and a bfg 7900gt.
 
from what i can remember yes, you can do SLI with same gen card. But the SLI will work at the speed of the slower one.

correct me if i'm wrong:confused:
 
i don't think so,

SLI requires same model of card, but not necessarily same clock speeds. that is where they dumb down so to speak.

so if you have a 7900GT you'd need a second 7900GT but manufacturer (evga, xfx, etc.) doesn't matter nor does the stock speed. the faster one just clocks down the same speed of the slower.

so no a 7900GT and a 7900GS don't play nice together. however, same card from xfx and bfg would.
 
I may b wrong, but from what Ive heard, to get the most efficiency(widout ocin) out of 2 cards in sli - they have to match.

Click to expand...

100% false. You can mix and matxh SLI cards that are different models, manufacturers, different amounts of ram (Lesser amount will be effective amount though).

So long as its the same physical GPU on both cards there is little else that will prevent SLI with different cards.

Although like said before when mixing 2 cards it will be the same as having two of wichever is slower.
