Seems ok but i would bump the core down to a i5 3570k when it comes out later this month (as i7s are generally not much better for gaming as hyberthreadings more for running several different tasks/ video editing.What about the Case,HD,OS u already got them and if u but be careful buying from WAEPLUS (seem to have very bad reviews ie taking weeks to deliver)
Agree that getting an i7 is pointless for gaming, if you're not waiting for Ivy Bridge get the i5-2500K.
Personally the only difference I can see between the motherboard you chose and the one below is that yours has 2 Firewire ports (1 on the back panel):
Asus P8Z68-V/GEN3 £120 http://www.dabs.com/products/asus-p8z68-v-gen3-s1155-in...
So if you don't need Firewire then the fact that it it cheaper makes it the better choice. Unless you know of another difference which is important to you.
