Dual graphics cards in same PC. Usage regulations and limits

by A-G- / April 1, 2013 6:18 AM PDT

I'm really not very familiar with installing two discrete graphics cards in the same PC, but the case is, i have a nvidia gtx 480, and rather than selling it, i thought of keeping it with new one which is the gtx 680, what's the odds of having them in SLI connection, and if not how can i be using them in the PC, what's the situation thn, and the regulations for different multiple cards usage in the pc

Not to be confused with fact.

If you want to run gpu's in parallel it's best to have a matched set.

The farther you move away from the "matched set" the more fuss-in might be needed to get the mix to play nice together.

I'm not aware of rules for gpu mix+match.

At the shop we would never mix and match except for fun to see if it worked. Most folk are on the verge of litigation so for them you take the party line of matched sets.
