Can someone please provide the resolution when set to 200% in SteamVR pre-update? My WMR updated and now it uses the new scaling which is higher than before. Now my 200% is in the 3000s which is way too high.
I suggest before upgrading anything, try overclocking you cpu first and see what kind of performance increase you notice. I had that chip before and had it overclocked @4.7 watercooled. Give it a shot before spending money on upgrades.
