ah ok so i wouldnt even be able to go 3 way with that chipset. i didnt look up the specs. my old i7 920 has 36 lanes i belive. so since i only have 16 lanes if i run both gpus at 8x each and use an expansion slot or something witht that use some of my lanes and lower the performance??
8x/8x is enough . i7 4790K beats i7 4820K with 40 lanes , in games There are other lanes in addition to these , Usually 8 - Z97,H97,Z87,H87, B85 . .. H81 chipset has 6 lanes .For 3 cards , i would get i7 5930K but the price of the rig gets too expensive .
