I hope the title is self explanatory. Vega 56/64 officially support CF, though actual support is a bit of a guess-game. Since used Vegas are pretty cheap atm, I thought I could pair my V56 Pulse (Samsung mem) with another V56 (preferably, if I can find one with Samsung HBM also) and wait till the first real Navi cards (afaik RX5700s is a hybrid generation) get rid of any early illnesses etc. I'm gaming on a 1440p/144Hz/FS monitor, so I could really benefit from the extra power. Looking around on the net, I found out that most DX12 titles are compatible(-ish) with mGPU setups and that there is a pretty good scaling, usually. Is there something that should completely discourage me? I have a Corsair D800 tower to house them, a 850W gold Seasonic PSU, a R1700@3.8 on a X370 Taichi. Any input will be appreciated. TY!
