Q's about sli:

[Sojuuk]

I haven't really kept up with the progression of sli tech but I recall talk of using different gpu's and manufacturers and whatnot in sli together. Did that ever happen?

if it didn't, can i just use 2 video cards not in sli e.g. 7800gt + 7900gto.(i have multiple screens)

You can use 2 cards as lo9ng as they have the same GPU. They can have different memory but effectively they will only use as much memory as the weakest link ie. if you have a 512 card and a 256 it will use 256 of the 512 card thus lowering perfomance you could be getting. Manufacturers dont matter at all.

I believe that the 7800 Gt and 7900 Gto are different GPUs so if not you cannot mix them.

That wasn't all of the OP's question. He's got two different video cards and he wants to run them in non-SLI mode. The good news is that yes, you can do this.
