I'm wanting to buy another gtx 460 and run it in sli. However i can not find a exact match to mine. So i'm wondering if i can use a overclocked or different bit 460 in sli. I have a basic 1 GB 675 core speed, 900 memory speed, and 1350 shader. It is also a 256bit most of the ones i can find speeds are alot higher and its 198 bit. Will it work with the higher speeds and lower bits?
