All three boards are good in their own right, I have the Tforce6100 and I love it, so I am biased in its favour. Running my Vencie e6 core 3000+ at 265mhzx10multi at 1.5v for the last 2.5 weeks now, Pc has never been turned off in that time, I have downloaded 25gigs of Data over my router, burnt about 50dvds, played Oblivion and tomb raider legends and it hasn't complained or hiccuped once. Probably one of the best mobos I have ever set up and owned in my opinion ( probably setup about 250pcs in the last 6 years) overclocks like hell, damn stable and is very cheap in price. Decent onboard graphics, supports all pci-express cards, sound is decent but not spectacular, good nforce driver support, excellent IDE and Sata performance.
just my 2 pence worth.
