>SupposedlyIvy Bridge. I recommend waiting for the release of Ivy Bridge at least before jumping the gun and getting an i5-2500k. It supposedly has better performance than Sandy Bridge so it must be worth waiting for
It absolutely will. The 2500k is a nice processor, but it's at that stage right near the end of it's prime where it still hasn't gotten a price drop.
Even if you don't want to pay for a fancy new Ivy Bridge processor, the sandy bridge ones will go down in price anyway.
