One thing about the motherboard. there are a lot of versions of the A8N. I noticed you linked to the A8n-SLI Premium.. check out the A8n32-SLI Deluxe. It's a huge improvement. You might want an add-in soundcard, since those NF4 boards come with AC97 audio. Other boards have integrated HD audio, like the Asus A8R32-MVP or DFI CFX3200-DR.
About the FX60 you say "what's everyone's opinion" -- if you want the highest possible overclock then go for it. Stock speed is 2.6, with 2.8 always attainable and 2.9-3.0 sometimes attainable. However, something like the X2 3800+ for $300 can reach 2.6. If you want the 2x1MB cache, you can go for the Opteron 165 or 170... are these things you've thought about?
To Davegod: if OP wants to go PCIe and dual-core, it's a significant upgrade from what he has... Conroe might be worth waiting for, but not really AM2...
