Right now I've got two EVGA GTX 980SC's on an ASUS Rampage V Extreme MB. I'm using slots 1 and 3 for x16-x16 and I've got one of the lighted EVGA SLI bridges, P/N: 100-3W-0032-LR, which is listed for 2 way/3 way SLI. It connects to both SLI connections on each card.
If and when I ever can get a couple of the GTX 1080's, will this bridge provide the same performance as the new HB bridges? I'm running twin, 28 inch, 3840 x 2160 monitors.
