I might upgrade if i5 2500k or better cpu could benefit me now and in the future. I might also get a second 7950 for crossfire once a price reduction occurs. I am thinking of spending about 800$ for a new build without a second 7950
Yeah you're better getting a second 7950 - my system right now runs a 1055T and swapping the CPU for an i5-2500K will not make that much of a difference. Sure the 2500K is great, but that money is best spent on getting a second 7950.
