I've been looking at the Phenom X6 1090T and the Core I7 870, the two CPUs cost about the same amount of money. Whilst there are motherboards for AM3 that are much cheaper than 1156 boards, the difference in gets fairly small when you go for the later AMD / ATI chipsets and want USB3 / SATA3, all in all the two platforms are close in overall cost but what about in terms of performance?
I'm upgrading to get more CPU speed for building software, i.e. multi-threaded compilation mostly under Linux, which one of the two will come out on top for something like a Linux kernel compile? The benchmarks I've seen suggest the I7 will win but I haven't seen a Linux kernel compile benchmark compare there two of them and thats really what I want to see!
Obviously, there is more potential to overclock the I7 than the X6, and the I7 will run cooler too!
