The 3570k had been released and i currently have a 2500k. The price of the 3570k is currently $190 dollars on microcenter.com right now. Is the 3570k a lot better then the 2500k or is it not worth the upgrade. And just a heads up if you are going to buy a 3570k or any of the I7 ivy bridges from microcenter you will get $50 off an intel LGA 1155 motherboard, Microcenter is having some crazy good deals
I'd say if you have SB just keep what you have. For people like me who are upgrading from a Core 2 Duo, go ahead and jump on board with Ivy Bridge so you can atleast gain access to PCI 3.0 for future upgrades in video cards. Thats just my 2 cents.
