Stay away from socket 1366. Go with an 1155 socket chip - the favorite is the i5-2500k. You'll obviously also need to change your motherboard to something with socket LGA 1155, also. The newest/best chipset is Z68.
The RAM you picked is dual channel RAM and you've picked a triple channel chip/mobo. If you go with your mobo/cpu then change the ram to a triple channel kit (6GB or 12GB). If you go with my mobo/cpu suggestion then dual channel is right. In that case, though, you might want to think about 8GB. RAM is relatively cheap and 4GB is cutting it close.
So if I go with a Asus P8Z68-V PRO mobo which has a 1155 socket and a Intel Core i7-2600k chip would it still be a solid system?
Since the new mobo is dual channel I can stick with the RAM I plan to buy and will buy two instead of one so the system will have 8GB in total
Thank you for pointing out not to go for the 1366 socket.
Yeah, you've got it right. An i7-2600K on a Z68 board is a great choice. If it's an option I would get a 2x4GB RAM kit instead of the 4x2GB that you mentioned. The performance won't be any different, but if you ever need to go to 16GB you can upgrade more easily.
The only other thing that sticks out to me is the PSU. OCZ isn't the best brand (though it isn't the worst either) and the +12V rail is a little underpowered (25A on each of two rails). I can't find anything that is both modular and more reliable in that price range, though.
