well, safe your money..
get a 8350, and decent cooler..you'll be able to touch 5Ghz clock without throw away too much money..
h60 is not good enough to handle 5ghz fx cpu class..
at least you'll need best air cooler available, phanteks ph-tc14pe, or even best liquid cooler (nzxt kraken x60 or corsair h100i/110)..
And, single strong card is much better than 2 weak cards run in crossfire..
more power requirement, excessive heat, microstutering problem (it'll really hurt your eyes), and troublesome setting..
i suggest you to take 7950 or better gpu, rather than 2x7850 in cf mode..
Thank u very much. i will consider this and look into the cooler and GPU-issues u pointed out.
