Building a performance/gaming PC

[hpfreak]

I've been putting together a desktop on TigerDirect.com
I'm pretty happy with the build. I just want to check with you guys if it the parts are 100% compatible with each other.
I'd like to add that I already have a 500 GB Seagate HDD and a Windows 7 Ultimate 32x license, along with a DVD ROM Drive, and DVD-RW, the hard drive is SATA, and the DVD Drives are both IDE.
Here are the links to the parts and the prices:

Motherboard and processor:

Total is 549.99 USD, including TAX, and shipping.
I don't want to spend anymore then that. But I'm open to any suggestions.

I'm looking for a high performance desktop with gaming capabilities.

Thanks,

If I forgot to mention anything important. Please ask me

Anyone? Please? I just need to know if the parts will work together. Mainly the PSU.

I realized that the DVD Writers probably won't work, considering that they are IDE, I will go ahead and get a cheap SATA DVD drive to go along with that.
