ive read a few forums regarding FSX and hyperthreading. I want to purchase the i7 3770K but i might as well just go for the i5 3570K. The only reason i want to go for the i7 is because its got HT. Now i know fsx doesnt really support that, but if you have two exact systems, with the exact OS, and fsx + addons, but only one has the i5 and the other the i7, would you see a fps difference when youre at a detailed busy airport with PMDG type aircraft or some place that the cpu is put to test, basically. And both are maybe oc'd to 4Ghz for example.
I dont want to waste an extra few bucks on something "bigger&better just because its an i7" while the i5 would and could do the same. On the otherhand getting the i7 obviously wont be a bad choice.
