What to do with a SIX CORE CPU?

So, I'm looking at building a computer for a friend. It's a desktop, and the project has me excited to examine the new hardware and price structures. So far, including the LCD (21 inch), the price comes out to a "reasonable" $866.91.

The CPU is an (AMD Phenom II X6 1090T Black Edition Thuban 3.2GHz Socket AM3 125W Six-Core Desktop Processor HDT90ZFBGRBOX) from newegg.com. And 6GB of DDR3 RAM.

QUESTION: What do you do with a X6 core CPU? Games are going to be fun, for sure. But what sort of server applications can be run on this sort of platform.

Here is the short list I can come up with.

1. TOR client, Linux flavor.
2. Polipo client, Linux flavor.
3. Virtual Machine running some flavor of windows, maybe XP or WIN7?
4. Apache Web Server.
5. SSH Server
6. Minecraft server (Linux)
7. BitCoin client, Linux Flavor.
8. Bittorrent client.
9. VSFTPD client.
