So my brother's i7 930 has died and I was wondering what a good replacement for it would be, he does heavy photoshop and rendering work. I was looking at the i7 3770k and the i5 3570k and I know photoshop takes advantage of hyper threading but the i7 is quite pricey compared to the i5. So any opinions on a good replacement, not necessarily the ones I've mentioned? And yes I do know they rest of the system has to be upgraded.
