I'd like to see the performance difference with an i3/i7 when the hyper threading is disabled. Would be interesting to see if there really is a performance gain purpoted by various intel fans. I also wonder if an i7 with only two cores enabled + HTing perform anywhere close to an i7 with four cores and no HTing.
Heck, maybe do a test with only a single i3 core with HTing enabled and then compare the results to an i3 with both cores and HTing disabled.
Preferably, the test be done on a variety of games.
But yeah, that's getting off-topic.
If the future is your concern, and considering how the next-gen consoles are utilizing octacore AMD proccies, it'd be a wiser move to go for an AMD 8-core. Like the 8320.
That's not factoring in that future-proofing is as perfect an example of a fallacy as one can be, however.
