I just built a system over Labor Day using the new MSI K8N NEO FSR mobo (Nvidia NForce 3 Gb chipset), Athlon 64 3200, and ATI Radeon 9800 Pro. All these items were on sale at Fry's :
MOBO + Athlon 64 3200 combo package = $269
ATI Radeon 9800 Pro = $199.
2 x 512 PC 3200 Corsair Value Ram = $90 each.
SB Audigy $39.
A few comments on this combo:
1) It screams. It overclocks well. I have my front side bus at 220 mhz (200 is stock). Rock solid. On the new SIS Sandra multimedia test it benchmarks faster than every reference system in the test, including all the dual processor systems, even the dual processor Intel 560 3.6 systems.
2) The mobo is picky about sound cards if you need the gameport to work for analog controllers. Some Audigy 2 gameports will not work. I had a Turtle Beach Santa Cruz, no way would the gameport work. I found the SB Live! would work, then tried a plain Audigy (not the 2); it works great. If you use USB HOTAS, this is a non-issue.
2) The mobo is set up for three sticks of RAM, but three sticks of PC3200 won't work, at least not with the current bios. Plan on buying two sticks. Three sticks of PC 2700 do work.
Before you buy, read the user forum of the board you are interested in. Here's the one for the AMD 64 Nvidia MSI boards:

One last word of advice, the Nvidia NForce 3 chipset is new. It will experience teething problems as issues are found and corrected in new bios updates. If you don't want to be on the new edge of hardware issues, get a board with a chipset that has been around a year or more. Those boards will have most of the problems fixed, or least you'll know the limitations going in.
