For the motherboard, get a Gigabyte if your on the cheap and Abit or preferably DFI if you will be overclocking.Good processer, just make sure to get the venice core, not sure if its out though but if its not then its certainly worth the wait. As for memory you don't need 2 gigs and if your gonna get Corsair then XMS is supposed to be good or you can get OCZ ram, G.Skill if you got the money would be good. As for your hard drive, make sure you get SATA. Seeing you will be using this computer for gaming, I don't suggest using that card. Instead get an eVga 6600GT. Don't use the PSU that comes with your case, your putting a good ammount of money into your computer so don't skimp out on your psu or you will regret it. I recommend an OCZ modstream for the price, or if you have more then Thermaltake and Antec power supplies. If you you get the DFI board and cannot fit the onboard sound plug in into your mobo for any reason such as it hits the fan like it did in my case, you can get a soundblaster live 24 bit which will do you well on a budget, or if you got a nice bit of money to spend a soundblaster audigy 2 zs. You didn't mention any cd drives so does that mean you already have them? All I can think about right now.
