First full build

I'm trying to build a PC that would mainly be used as htpc but i do like to game occasionally. My budget is $1000. Because of the shipping costs newegg is about $1100 for what i think i want and micro center is about $975 for the same parts (I'm trying to squeeze out every cent i can) and they have in store pickup unless there's any reason i shouldn't buy from there. Okay so this is what I'm thinking

ASUS SABERTOOTH 990FX R2.0 AM3+ ATX AMD Motherboard
$134.99

AMD FX 8320 Black Edition 3.5GHz AM3+
$169.99

Sapphire Technology AMD Radeon HD 7850 - 2 gig
$204.99 w/ mir makes it $189.99 (if it works which is always a hassle)

Corsair XMS3 Series 16GB DDR3-1600 PC3-12800) CL 1
$79.99-$69.99 after Rebate

Corsair Hydro Series H60 High Performance Liquid Cooler
$65.99

Corsair CX Series CX600M 600 Watt ATX Modular Psu
$79.99- $59.99 after mir

LG 14x Internal Blu-ray Burner WH14NS40
$69.99

Cooler Master CM Storm Enforcer Mid Tower ATX Gaming case
$77.99

Pretty set on and unless there's a big difference with Intel. I have a amd phenom 940 x4, gigabyte mobo, and radeon 4870 1/2 gig ddr5 and 4 gigs of ram. But i can play dead space 2, mW 2 on medium settings with no lag in 1080p on a 50 inch plasma. So since most of what i read says i shouldn't really be able to play those games on that rig...so i like amd for that (running stock not over clocked).
So any advice or insight would be greatly appreciated.
Thanks
