well ive been trying to work it out myself lol, id say that most of the time it's not using over 60 - 70%, it is clearly more bottlenecked on GPU/PCIE lane's more than the cpu, although it is clearly an upgrade though & remember that 7990's only really grunt @ higher Res & im on 1080p for now rolleyes.gif

when gaming not all cores are getting used most of the time, they are parked?

oh & another thing ive found is having the 2 has sort of reduced the core temps, guess its spreading the load making them run cooler. I am running it now with the side panel off though?

@ shooter FX your X79 would do it more justice & your cpu will be fine.

magicase im looking @ it like this, yeah its not performing to it's full potential, its about the same as 2 780/titans, im gonna wait for haswell-e to upgrade the cpu/mobo, then it should really grunt lol.

as authie said you may be better off just getting a 7970 & doing trifire? its cheaper & more or less going to be the same? I just wanted to try quadfire for the first time really.

if I was going to buy new now the 290x's are out id still probably get the 7990's not much more power usage, 8.2 TFLOPs compute power,& when mantle comes into games it should really shine?
