I own an AMD 1055T myself. I had it OC'd to 4.09Ghz stable but turned it down because that amount of stress is unnecessary for what I use my compy for.
I mention that because I've always been an Intel guy, but recently went AMD for purely budget reasons, and I must say, I've been very happy with my CPU.
Also, one of the selling points for me was that the 1055T score about 600 points higher than the other cpu I was looking at, the i5-760, on this chart:
http://www.cpubenchmark.net/high_end_cpus.htmlThe six-cores work great for me because I do a bit of multi-threaded applications (and also wanted to futurize my rig,) and I was absolutely floored when I saw how much faster it did things than my old 3Ghz Pentium 4 w/HT (which scored about 1/6th the score of the 1055 on that chart.)
If you decided to go AMD, you could get the Phenom II Advanced 945. The 955 and 965 are black editions, so you'd pay more $$ for an unlocked multiplier, and then you have the 1035, 1055, and 1090, which are all hex-cores.
That being said, I highly doubt you'd be disappointed with the i5-760, as I tend to agree with people that they seem to be more... resilient?
That being said, it's much more important to have a sweet graphics card than a sweet CPU when talking about gaming.
