If you really want to pay £600+ for a CPU, then you are way out of my league.So would like to go for an i7 - Extreme the 990 being the biggest and best I believe.
As GHD indicated i7-2600k is the way to go for about a third of the price. I've read that the I7 series on the 1366 socket are going the way of the dodo. They are not for gaming but workstations.
And read the conclusion of this review
. Looking at the benchmarks, I have no idea which one might be relevant to FS but none show enough difference to justify £600+.
Instead that extra £400 could be used for graphics cards, SSDs, etc. Otherwise as SkippyBing said
, I too can help with that problemunless you're allergic to money, in which case I may be able to help
