<$800 gaming build

So I struck out to build a gaming PC <$800

I will be resuing a full tower, 22" inch montior 1680x1050, keyboard, mouse, speakers.

I would like very quiet PC. I chose the barracuda, CPU cooler, and PSU all for their relative performance/value/sound levels.

How loud is the GPU I have here?

Everything priced on newegg.com. Check Amazon and TigerDirect, but didn't see anything better priced.

8 gb of memory may be a bit high, but I have 4 DDR2 slots to fill on the Mobo and want more than 4gb.

Here's what I have:

CPU: AMD Phenom II X4 940 3.0ghz

Motherboard: Biostar TA790 GXB AM2+ (no SLI or Crossfire) 4 DDR2 slots up to 1066

CPU + MB - $202

GPU: eVGA GeForce GTX 260 Superclocked

Memory: 8 GBs DDR2 1066 OCZ Reaper HPC

GPU + 4gb Memory: $202
Additional 4gb Memory: $44.99


Cooler: Coolmaster Hyper tx2

$19.99

PSU: 700 watt OCZ ModXStream Pro 80 Plus certified

$70.99

DVD-RW: LG DVD Burner

$25.99

Wireless Card: ENCORE ENLWI-N PCI 2.3 Wireless Adapter - Retail

$24.99

OS: Windows Vista Home Premium w/ free upgrade to 7

$100

Hard Drive: Seagate Barracuda 7200.12 1 tb

$87.99

Total cost pre-mail-ins: 879.51
Total cost after mail-ins: 779.51

What do you think? Biggest weakpoint IMO is the motherboard...but that's a major $$$ saver (Bundled with the CPU, only costs me $10).
