First time building computer

[Rina744]

Hey, I'm going to build a computer but it's my first time doing it by myself so i could use some tips.

Here's what i've put together so far:

COOLER MASTER Elite 430 Case
http://www.newegg.com/Product/Product.aspx?Item=N82E16811119227

AMD Phenom II X4 965
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103727

Rosewill Tachyon Series Tachyon-650 Power Supply
http://www.newegg.com/Product/Product.aspx?Item=N82E16817182272

SAMSUNG 840 Series SSD
http://www.newegg.com/Product/Product.aspx?Item=N82E16820147188

Seagate Barracuda 1TB hard drive
http://www.newegg.com/Product/Product.aspx?Item=N82E16822148840

ASUS 24X DVD Burner
http://www.newegg.com/Product/Product.aspx?Item=N82E16827135204

ASUS P8B75-V LGA 1155
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131835

SAPPHIRE Radeon HD 7750
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102969

G.SKILL Ripjaws X Series 16GB (2 x 8GB) memory
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231486

I think that's everything. I want my computer to be under $1000 preferably around $500 - 700 so if you know anything that's just as good but cheaper that would be awesome. I do a bit of gaming so i need it to be nice enough to run stuff like Starcraft 2 and not just on the lowest settings

I like that site Thank you!

I I like the new prices, except the cpu seems not as good for the money, but im thinking i'll downgrade the ram and add a couple more sticks if i need it. I like how much cheaper the power supply is. Will the computer run just as well with less watts?
Also, the video card is 2x as expensive as the one i had. Is it that much better?

I have the mouse and stuff, and can get the os through school
