uhhhhh are there programs that still use single core performance these days? also I checked the benchmark pages and videos... the 6300 handles crysis 3 pretty well stock clock
Last gen games, every single MMO and basically everything not made in Frostbite, Unreal or Cryengine still relies on dropping lots of stuff on one core.
BTW, Geforce website itself says my GPU needs:
Minimum Recommended System Power (W): 500W
And it's a lie, anything more than a decent 600W PSU is absolutely ridiculous for a single GPU build.
Just to put it in perspective, a system with the fastest desktop CPU (i7-4960X with some decent overclock, 4,2Ghz to be precise) plus the fastest gaming GPU in the market (Titan X) draws 392 Watts from the wall when playing Crysis 3, the whole system.
