buy the cheaper i5 but a better graphics card (gtx 580/590)
the i7 is not made for gaming, the i5 is far better

and maybe take a look at cry-adams specs, he got a really nice combination
also 9GB ram is too much. if you want to waste money - go for it. but 4GB is far more than you will ever need!
+the 460 is too weak to run crysis 1 maxed out on a really high resolution. its a mid class graphics card and if you read some benchmarks you'll see that im right.
the system you made sounds like expensive alienware ****. custom pc ftw!
