i7 is pointless in gaming, i5 is more than powerful enough, and i don't thing any games are threaded for 8 cores so it will recieve no benefit other then a lightened wallet, and 2 5770's would be more than enough for any game for a little while if overclocked, and 4gb's of ram is more than enough for almost anyone, only people running multiple windows of very heave programs need 8gb's of ram truly, it is good to have but unnecessary, and i don't think it's easy to get 8gb sticks, or if they even have them for desktops.
