I already have a 1070 with my 6700k.but i am building a duel xeon rig and it's ether going to have crossfire 480's in it or sli 970's.
Still trying to go over the 480 benchmarks in Doom,witcher,overwatch and CS go and compare them to 970 benchmarks but form what I've seen in Doom
the 980 has a good 25-30fps over the 480 with it beening stable at 105ish and highs in the low 130's. The 480 is stable around 75ish with highs in the 100fps range. The 970 i'm not so sure as it's not the same Location but it looks to be maybe a touch slower but it does not have the dips like the 480.
What do you think about the benchamrks? The videos are back up now at WCCFTECH
