I am considering purchasing an LGA1155 board but dual GPUs they only run at x8/x8.
From my research it seems that you lose about 1-3% tops when running at 2500*1600 but a lot more when running games over multiple monitors / bigger resolutions.
My setup will be to only ever play games on my 30" (2500*1600) but I will have up to 4 additional monitors on at the same time, just not rendering the game. Will this cause more performance loss. Also, all the tests I could find were on last generation GPUs and the most current will use even more bandwidth?
Realistically, with multiple monitors but a game running at 2500*1600 using two new generation GPUs what performance hit should I expect to take with x8/x8 vs x16/x16?
