[sarcasm]No, this one owns them all:
Intel 8088, 4 MHz
ATI Radeon 9800 XT 256 MB w/ AGP converter

Uhh... the A7N8X Deluxe cannot support Athlon 64/64 FX processors (different architecture + form factor). The K8V (VIA) / K8N (Athlon 64) or SK8V (VIA) / SK8N (nForce3 Pro-150 - Athlon 64 FX) might be one of the optimal choices for a single 64-bit CPU.
If you're seriously looking for a motherboard w/ support for Dual Athlon XP/MP processors, look for one based on the AMD 760MPX chipset.
Unfortunately, if you want to go with the Athlon XP 2600+ Barton w/ 333 MHz FSB, the 760MPX only has support for the 266 MHz FSB variant (based on TBred-B).
Your call on this one (single vs. dual vs. hyperthreading).
