I'm trying to build A Desktop Gaming computer

[Synge]

Good luck man, if you have any questions about compatibility be sure to ask us :]

On-board audio is good enough these days that it's unlikely you'll here much of a difference, so I wouldn't bother with a sound card.

These are the optional stuff:
- CPU Fan/Heatsink

Also, don't take this the wrong way. He means aftermarket coolers. Your CPU will come with a heatsink, definitely make sure you put that on :P
