For me on a 1700, not much has changed, i switched to the K7 from a Prime kinda early on (around when the F6 was released) and 3200 worked straight out of the box, general impression then was Gigabyte were ahead on the RAM side compared to the others, but lacked options.
Now the other boards have improved/matched or surpassed now on the RAM, and we still lack the extra options (whether they are needed is up for debate) but generally it feel its been left behind.
F20 gave some extra dividers, was able to creep up 3308 (ie 101 x 32.66) but the main bit, its at least stable! (depending on BIOS, and touch wood)
F6, F7a, F10 was fine, F20, F21 and F25 have been good.
F22, F23 and F24 have been terrible (again for me)
