Hex cores are fine, however realize they are no faster with one or two threads than a quad at the same clocks. So don't get a slow hex and expect it to perform better than a fast quad (except in highly threaded environments). Also note the T on the end is Turbo, so compare the Turbo frequency with quad CPU frequency (when determining single thread performance).
Only OEMs use the 1035T IIRC, which I wouldn't suggest. How "excellent" are the other parts anyways? How much is it?
Hex-cores are good, but as of now has has no impact on games what so ever (both good and bad). The fact is most games now use barely 4 cores (contrary to what you hear), so you'll see no performance gain from a 2.6Ghz Phenom X4 to X6.
Regardless, it is a nice 25%-30% increase even in single threaded performance over the 5000+.
