Granted in your case not a big deal, neither for me at this time. If I keep my next motherboard for 5 years and want a 2 gpu option, it might be an issue. In which I would just upgrade if needed. At this time I don't see 8x/8x SLI as causing any significant performance disadvantage and I will be doing just that hopefully shortly with RyZen.I'm glad I can play DaVinci Resolve.... is that multiplayer?
It's a small margin, for an even smaller margin of the market, some "Achilles Heel". Bring it back when AMD makes a fuck up like pinning their CPU's to RD-RAM that costs more than their competitiors whole CPU+MOBO+RAM combo.
