I was considering another 560ti card and upgrading to sli for BF3. I already run a 560ti now and was wondering how much more performance this would give me. Can someone give me an idea if this would be cost effective?
When both PCIe X16 slots are populated on that board, they both run at X8 bandwidth. Still faster than those cards will need for PCIe ver 2.0.
With 2 cards, you will get an average of an 80% boost in frame rate with most games. I have that same board with my 2 x gxt 570s. (see my sig) There's always the possibility of micro stutter with dual cards in some games. But so far I haven't noticed the effects myself.
