Haswell will be a good upgrade for you. People expressing disappointment here are mostly talking about improvements over the last couple of i5 and i7 series CPU's.
I've been running an i7 950@4Ghz for the past couple of years on a ga-x58a-ud3r. Was planning on buying an Ivy a few months back if it wasn't for Haswell on the horizon.
Anyway, just placed my order
