Trying to build on a budget

[bluearth]

Processor
$190 - AMD Phenom II X6 @ 3.3 GHZ 1100T - INFO

- I went 6 cores to try and future proof myself.

Motherboard
$140 - Gigabyte AMD 990X + SB950 AM3/AM3+ SATA 6Gb/s USB 3.0 ATX AMD Motherboard GA-990XA-UD3 - INFO

Key reasons I chose this motherboard:

- 4 memory slots for future expansion (up to 32 GBs)
- AMD Phenom II support
- 3 PCI express, one 16x and another 8x. Two 16x slot boards were $70 more.
- nvidia SLI support when I add a future GTX 460
- 6GB/s SATA support
- 4 USB 3.0

Graphics Card
$150 - EVGA GeForce GTX 460 1 GB GDDR5 PCI-Express 2.0 - INFO

- Best performance in its price range.
- I like how it comes with a HDMI miicro to HDMI adaptor

Operating System
$95 - Windows 7 Home Premium SP1 64bit (Full) System Builder DVD 1 Pack - INFO

Hard Disk Drive
$55 - Seagate Barracuda Green 1.5TB 5900RPM SATA 6Gb/s 64MB Cache -INFO

- 6GB/s SATA takes advantage of motherboard's 6GB/s SATA
- fast 64MB cache
- 5900 should be stable
- best 1TB+ HDD in this price range IMO

DVD Drive
$20 - Sony 24X SATA Internal DVD+/-RW - INFO

Power Supply Unit
$65 - Corsair Builder Series CX600 600 watt - INFO

- recommended PSU for my setup is 425 watts. 530 if I go SLI. So I went 600

Memory
$73 - Corsair Vengeance 8 GB ( 2 x 4 GB ) DDR3 1600 MHz - INFO

TOTAL
$788

I have a few old PC boxes laying around will use one of them

Any problems?
