Help with a build/upgrade

[PapaSpeedy]

I’m planning to upgrade my current pc and get rid of my old set up which is a
QX9770 on a Asus Maximus II board with 8gb dd2 ram, cpu cooler is the cooler master V8 and PSU is Antec 750w, GTX570 and 2x 1TB HDD all in a cooler master storm case.
I’m planning to get the Gigabyte Z77X-UD3H Intel Z77 (Socket 1155) with 8GB ram, The H80 for cooling and reuse as much of my old parts as possible.
I do not know which CPU I should get that will suit me. I’m looking at the 2700k and the 3570k which would be good for gaming with a overclocked to about 4.0 - 4.2.
I play games like BF3, DCS A10 Warthog, Dirt 3, F1 2012, FSX and want a set up that will last for a while without hitting my pocket hard.
Any advice would be great

Thanks

Ok thanks will do then so keep my CM storm case, The antec 750w true power psu, and my hard drives and gfx card.

So all i need is the CPU i5 3570k, board gigabyte z77x-d3h and 8gb ddr3 RAM. What RAM make would your recommend cosair or kingstons? also instead of the H80 what other good coolers would do for a over clock @ 4.2
