That would be their GTX 780 Ti.
Just get whatever is the latest. I keep losing track of them.
True Geoff, but if you can save money and not lose out on a lot then you may as well just get the i5. You're not gonna notice a difference between 6 and 8MB of cache and you could buy an awesome cooling setup for the $100 you saved and get a 4670K or a 4690K to well over 4.0GHz. And as for HT, yeah it's nice but for gaming 4 cores is enough.
But if money is no object, then just get a 4960X, right?
Or if you must have the i7, get the 4770K or the 4790K or whatever's the latest one today...
