eveything is great if you got the money, but a word of advice, that mobo is a dead-end in terms of upgrade, its the last in it's line, plus, its abit of an overkill if your not going to OC. go with a P5N32-E, you'll save quite alot and still get 2 x16 slots.
that PSU is just sick overkill. a system like that, running with even GTX's in SLI we'll need a 700W PSU. max
it's a total waste of money
