Best answer for first helpful answer, thanks all.
I went out and bought the IB i5 with an AsRock Z77 Extreme4.
Boy do these run hot!
I can easily get a stable OC @ 4.6Ghz, but it just runs too hot.
Heard about the thermal paste being used etc, but not going to 'pop the hood'. ;p
Doing perfectly fine @ 4.4Ghz, no (manual) voltage OC, nice temps, good performance.
My 7950 @ 1075 / 1433Mhz, just below what's stable in 3dMark11, as before.
It's running great guys, the performance increase in GW2 is quite significant.
I'm running up to 100fps (checked real quick with Vsync off).
Of course I still have a couple of fps dips here and there, but that looks to be mostly because of loading stuff, as they're really short.
Perhaps I can minimize that a little with an extra SSD and put them in striping config.
