how's this build look?

I am building a new computer for gaming. I'm keeping my monitor, keyboard/mouse, speakers and dvd drive/dvd burner. I need everything else. I have about $1100 to spend.


COOLER MASTER RC-690-KKN1-GP Black - 3 120mm fans, good rating

G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 800 (PC2 6400)
(http://www.newegg.com/Product/Prod [...] 6820231098)

GIGABYTE GA-P35-DS3L LGA 775 P35 motherboard - going with this instead of the DS3R because I don't think I'll need the extra ports that the DS3R has. unless it has other features I'm missing

Seagate Barracuda 7200.10 320GB 7200 RPM SATA 3.0Gb/s Hard drive
(http://www.newegg.com/Product/Prod [...] 6822148140)

eVGA 8800 GTS 320 MB - I'm running in 1280x1024, so 320MB should be enough right?

Intel Q6600 CPU G0 Stepping

Tuniq Tower 120 CPU Cooler

Does this look alright? Am I missing anything important?

Thanks for any help.

looks very nice, Seagate is very good , dont change it , (although i like WD too ) , if u can afford 8800GTS 640 ,then go for it , but for resolutions lunder 1600x1200 , 8800GTS 320 is fine and is equal to 640 in many games

It's beautiful.

I think I'd still go with DS3R. It has better onboard audio, better components, RAID support, and you can have more than 4 SATA devices. Of course, if you have a soundcard and only 1 hard disk/1 DVD and don't care about RAID and you intend to get a new motherboard in two years or so anyway then all these advantages are useless.
