New Computer Build

[lab_music]

Hello,
I am building my first computer and am looking for advice on the components I have chosen. This is what I have so far:
Power Supply: PSU-COM680-BK-US 680W ATX12V http://www.newegg.com/Product/Product.aspx?Item=N82E16817709023

Processor: i5 750 http://www.newegg.com/Product/Product.aspx?Item=N82E16819115215

Motherboard: GA-P55-UD3 http://www.newegg.com/Product/Product.aspx?Item=N82E16813128412

RAM: Crucial 4GB http://www.directron.com/ct2k25664ac667.html?gsear=1

Video Card: 5670PE51G http://www.microcenter.com/single_product_results.phtml?product_id=0328301

Hard Drive: WD Caviar 640GB http://www.excaliberpc.com/585652/western-digital-caviar-blue-wd6400aaks.html

Keyboard and Mouse: http://www.overstock.com/Electronics/Logitech-920-000383-MX-5500-Keyboard-Mouse/3457348/product.html

Fan/Case: RAIDMAX Tornado ATX-238WU http://www.eworldsale.com/raidmax-atx-238wu-tornado-atx-mid-tower-gaming-caseblue_8661_42327.html

I would like to use my current CD/DVD player but if it won't work I will get this one:
CD/DVD: AD-7261S-0B http://www.newegg.com/Product/Product.aspx?Item=N82E16827118040

What do you think? Is this the best I can get for the price? Is there enough memory and storage or are there components that are not compatable?

Thank you for the help

Update:
After looking into a couple more options, I now have:
Processor: AMD Phenom II X4 955 Black Edition Deneb 3.2GHz
http://www.newegg.com/Product/Product.aspx?Item=N82E16819103808

Motherboard:MSI NF750-G55 AM3 NVIDIA
http://www.newegg.com/Product/Product.aspx?Item=N82E16813130235

or

Gigabyte GA-MA770T-UD3P
http://www.eworldsale.com/gigabyte-ga-ma770t-ud3p-socket-am3amd-770ddr3a-gbeatx-motherboard_5751_42207.html

Power Supply: SeaSonic SS-650HT 650W
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151091

or

COOLER MASTER Silent Pro M700
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171037

RAM: Corsair 4GB
http://www.newegg.com/Product/Product.aspx?Item=N82E16820145218

Video Card: POWERCOLOR PCS+ AX5770 1GBD5
http://www.newegg.com/Product/Product.aspx?Item=N82E16814131327

or

EVGA 01G-P3-1371-TR GeForce GTX 460
http://www.newegg.com/Product/Product.aspx?Item=N82E16814130565

I figure I will stick with the previous case and hard drive unless I get too many good arguements to the contrary; in which case, I will probably go with the antec 300 case.

The ram usually isn't good. and you may want a better GPU.
try this ram http://www.newegg.com/Product/Product.aspx?Item=N82E16820231303&cm_re=g.skill-_-20-231-303-_-Product

and this GPU http://www.newegg.com/Product/Product.aspx?Item=N82E16814131327
