You should also notice that the high end Socket 939 processors are 90nm SOI, vs high end S-754 which is 130nm SOI, and thus S939 will (over)clock far better and/or use less power than their 'equals' on Socket 754. As Socket 939 has 6.4 GB/sec available it will scale better, and still be 'decent' come 2008.
There are also unoffically AMD Athlon™ 64 2800+ for Socket 939, aswell as a special AMD Sempron line for S-939 (HP + Fujitsu have supplies).
It is for these reasons why I pushed Socket 939 so much, in 3 years a dual-core Athlon 64 X2 / FX-60 (depending on availability, make sure to upgrade before they get harder to find) will not be such a bad system.
In 3 years a single core Athlon 64 3700+ will not feel so quick IMHO.
You could've just checked here:
http://www.amdcompare.com/us-en/desktop ; filtered by socket type and checked the highest and lowest models to get the range.

However, DDR2 (albeit DDR2-533 most likely for you) on an Intel Socket 775 platform, with upgradability to Pentium 4 Cedar Mill die (PreScott at 65nm, with lower thermals and power usage) will also be a decent upgrade. Of course the AMD Athlon™ 64 X2 4800+ (Dual-Core) would still give any Socket 775 system a run for its money, even when using DDR1 / PC3200.
It is a tough choice, as DDR2 means you can swap the board and likely keep the same RAM in a future upgrade. But depending what you want by that time you may be trying for two PCs, and more than happy just having a PCIe x16 slot + decent PSU in your 'older' system. In 3 years time what sort of money do you expect to have ?, Will you need to scrounge, butcher & salvage parts still ?, or will you have enough money for 2 decent PCs, one using whatever RAM / Socket is 'hot' come 2008 - 2010 ?
However, Having DDR2 would be good for the Intel Conroe upgrade, that is true, but they are due out in 6 months (Q3/Q4 2006), not 2 to 4 years.
😛 - We may all be on XDR RAMBUS by then for all we know :?:
(Even with shrink font that was long, too bad can't do two columns w/o using screenshots
😛)
As above, we may be on XDR by apx~ 2009, and you've mentioned 'new board and RAM' for a future upgrade / system (further off):
Refer my previous post:

It might end up +10-15% over your desired TCO with said parts, but with GeForce 6800 GS/GT you'll get +85% (or more) performance over a lesser video card (eg: GeForce 6600 GT) when paired with those parts.
Not to mention: You don't need a video card with that board to start with, just save the 'little bit over
total cost' it will be to get a __800 GS/XL series card, or GeForce 7600 GT if you can, and in the mean time 'settle' for the GeForce 6150 with 6.4 GB/sec. It isn't the greatest 3D video performance, but it isn't half bad either, esp as a temporary makeshift GPU while saving a little extra. (+15%, or so, extra cash 'all up' for double the gaming performance is well worth it IMHO).
Sure
card for card the GeForce 6600 GT looks nice,
but when you compare total system cost w/ 6600 GT (and not upgrading to _800 GS/XL series) vs total system cost w/ 6800 GS, and then compare their respective performance differences... well you'll see what I mean when you do it. 8)
PS: My pick for case + PSU combo is the Antec TX640B, it will last, and has damn good ventilation + enough of a PSU to get you into 1 x GeForce 7900 GT / 1 x Radeon 1900 XT territory - If you ever get a chance to do that:
