Review of Parts For First PC Build

I am new to pc's and would like a review of the parts that I have selected based on personal discretion and help from other forum members. Any advice on compatibility would be greatly appreciated; as I wouldn't want to order anything without knowing it would fit together. I am only missing a DVD-Drive.

It would help if you answered this, mostly to get a clear budget: http://www.tomshardware.com/forum/ [...] ild-advice

I strongly recommend getting a decent motherboard (maybe a Gigabyte Z68A-D3H-B3) and a 2500K. That processor overclocks beautifully, so when it starts to feel balky in a few years you can get a whole bunch of new performance out of it for free. Also, it's $180 if you can get to a physical Microcenter store.

Google is your friend. The 2500K is Intel's second-best LGA 1155 processor, and effectively tied for best in gaming. It's overclockable, unlike the 2400 (your original choice), so you can get a bunch of extra performance out of it for free.

Any reason you've linked to Circuit City for all your parts? Newegg is reliable and has great customer service.

The Gigabyte motherboard is not a hard drive. It is a motherboard.

Yes, it's compatible with the 2500K.

It should be no problem at all with a 2500K. You can just change the multiplier to a number that you know will work, like 43 (for 4.3ghz), without messing with voltage and other settings.
Use Newegg.

It happens in the BIOS, which is the odd screen that comes up after you hit the power but before you get to Windows. You'll have to hit some key, which will be indicated on the screen, to access its menus. This is often Del, but will sometimes be F10 or some other key. The CPU multiplier should be an easily-accessible setting.
