Hey everyone, I want to know what you all think of my possible build. I'm gonna be ordering all of these parts in about 6 weeks *crosses fingers*. Here's the specs:
 
Antec EarthWatts 650w PSU - Environmentally friendly  
Antec 900 case
EVGA Nforce 750I SLI FTW
Intel Core 2 Quad Q9450 with Thermalright Ultra-120 Extreme and Antec TriCool 120mm Blue LED fan
BFG Geforce 8800gt OC 512mb-I'll eventually go SLI
G.SKILL F2-8500CL5D PC2-8500 2GB 2X1GB-Eventually go to 6GB
Microsoft Windows Vista Home Premium 64Bit
500GB Seagate Barracuda 7200.11
 
Total: $1,300 CDN
 
I know I probably don't need quad cores for what I do but I only get a new computer every 5 years so I want to future proof this while spending minimal money. Games and other applications will eventually use all cores so it might be overkill for now but it'll pay off later. This computer will be my family computer and my desktop for when I move out. I need this for homework (documents, multi-media, ect...) playing games (UT3, Crysis, COD4, UT2004) watching HD movies, video encoding, downloading files and a lot of internet surfing. This is a future proof build so I don't need to hear about how I would only need 2 cores.

Look into getting a Corsair TX 650W or 750W (better quality) PSU.
What's the price difference of BFG 8800GT OC to a cheap 8800GTS ?
Get 4GB (2x2GB) DDR2 800MHz C4 (Corsair, Geil, ...) RAM.
 
Random other thoughts:
I would pick an ASUS P5N-D over the EVGA board.
I would pick WD6400AAKS over the Seagate.
