An i7 930 with a 5770 = bottleneck (unless you don't game)
if you wait one more month you will have more CPU choices and hopefully better pricing.
And maybe some extra saved money as well.
If the i7s drop when Thuban releases and you (OP) save a little bit you can get a nice GPU to go along with the beautiful 1366 setup.
Or flip side maybe Thuban itself will tickle your fancy.
