I currently have an XFX Geforce 7900 GTX (YDER). Factory clock speeds are 675mhz CPU & 850mhz (1.7ghz) memory.
My question is if i want to upgrade to SLI do i have to get the EXACT same card as above or can i get a card with different clock speeds? Would the faster card just lower its clock rates to match that of the slower card?
I guess my question is... How identical do GFX cards have to be in order to be able run them in SLI mode?
