Unless you want to buy an SLI motherboard later in the future and Rebuild the whole thing again, dunno, might be better to just get one now. The ram is decent for the price.... But in my opinion, The processor kinda sux... lol.
Heres a better ram.... well a bit better than the other and cheaper (after rebate).

Dunno if you're interested, but I got this for my sister, works great for its price. ($109, 2.8GHz, 2x 2mb L2 Cache, Duo-Core Processor)
That processor you're buying for $90, is a rip off >.>. 2.0GHz and 1mb L2 cache, that really sux ass...

Also.... The video cards(2) I'm getting, $109 after rebate. Same price basically as yours, but better.

And just like Zero said, Power supply matters a lot, better trust a good company... like this. (Rosewill)
