gtx660 sli help

post #1 of 2
Thread Starter 
right now i have a evga gtx660 superclocked signature 2 2gb. if i were to sli would i need the exact same card? i was looking on ebay for gtx 660s and it would be cheaper for me to just get one and sli it. so what are the rules for mixing cards or can it not be done. do i have to have any 660 with 2gb or what?


my card

Those 2 cards shouldn't have any problems in sli since both are 192-bit with 2GB VRAM and 960 cores. Card mixing is very limited on the nvidia side AFAIK, with the only differences allowed being the VRAM size, even so the sli configuration would run in the card with the lowest amounts of VRAM. i.e. if you sli a 2GB GTX680 with a 4GB GTX 680 the extra 2GB in the 4GB 680 would be ignored.

Anyways I think your better off buying a new graphics card rather than invest in 4 year old cards. Something like the upcoming RX480 would be a huge upgrade over even 2 GTX 660's.
