/me suggests you look at his sig.
Seriously though, the more I look at it, the harder it is to tell people whether to go with Socket 939 or wait for AM2. Future proofing is good, and so far I've told people to wait if they can. But, it doesn't look like the first revision AM2 setups will have better performance than 939 (some reports like Anandtechs indicate it could be worse until high-clock processors are available, which you might not want to lay the cash out for), and that AM2 will not truly mature as a platform until sometime in late `07, even if it is released now. Whereas Socket 939 has become a very good platform already.
I've only had my dual-core CPU for a week now. I have found some interesting quirks (Thunderbird had a bug I had to download a patched .dll for, had to upgrade my xVid codec since the old one would bomb out at the end of a video so I couldn't close Windows Media Player), but overall I like it. I haven't done any video encoding yet with it, but it's supposed to be smashing at that. I've had to do less of that since I got a DivX-capable DVD player and a ReplayTV.
Buy lots of RAM so your cores don't have to fight over available resources. My 2GB upgrade is even more recent than the CPU; got a deal at Outpost.com.
Oh, just curious...sure you need an SLI board? I bought my board knowing I'd never need one, and I'm still very happy (it has every other feature). Though it is true that it's harder to find full-featured boards that aren't SLI. I'd make sure that whatever you get, it still has a full 3 PCI slots if possible (two of my three are full, and I like headroom, since there are so few PCIe expansion cards out there).
