Update, this I posted on the other Topics.
Intel is pushing the latest Sandy Bridge E, Socket 2011 which I think is overkill for a gaming rig. There maybe some benefits for gaming as the CPU chipset supports
PCI-E version 3.0 which can be used by the latest top end video cards.
I usually spec a Z68 Mobo, Socket 1155, Sandy Bridge i5 2500K or i7 2600K, (if games being played are Multi Threaded). The higher you go with cost there is a diminishing performance return.
I would suggest deferring for a month as Ivy Bridge is confirmed due April. Some will operate on existing Z68 Motherboards
Or look at Z77 Motherboards, already available, like this http://www.asrock.co...=Z77%20Extreme4
