I just dropped a C-note for an 8RDA+ (arrives Tuesday...) after months of considerations for my upgrade. Wanted an alternative to VIA, looked at K7S5A, but didnt like the memory limitations. Leaned toward MS-6561 with PC2700 support-- but it lacked 333 FSB.
Thought I would have to go with a KT333 or 400, but then took a good look at Nforce2. Liked what I saw. For me, Epox was the only way to go when considering overclocking. Would've liked S-ATA onboard, but I will have to settle for an add-on card (which i guess is ok-- gotta find some use for all those PCI slots...).
Really, any Nforce2 board will do fine. Go for the non-plus version to save about $15 if you want (as long as you invest it in cooling).
