The Thermalright Ultra Xtreme-120 is the best, in my opinion, but it requires a little extra work. Here's a video on Lapping one for maximun performance.
The Motherboard has on-board HD Audio which is pretty good. Most people skip a sound card and you can always buy one later if your not satisfied with the HD Audio
On the SSD note, I got 2 120Gb OCZ Summit drives and I gotta say I'm extremely happy with them. Data transfer between them is like nothing you'd believe. And with a budget of 3000 you can def afford them.
