Hi guys. I've recently built the system above and had a couple doubts. My mobo has gen 2 pcie lanes (one 16x, one 16x running in 8x) and, while the gtx 970 has been a total beast ( my old laptop is Asus x50gl), I've been looking into sliing it. Will the second gpu be limited for being an 16x gen3 card running in an 8x gen2 slot? Would it be better to invest in a 990fx mb to max out the increase.Thanks in advance

2.0 8x, 8x sli is fine, more than enough

2.0 8x, 4x would cause issues though.
