Well, not sure these strictly are point-buy, but at least they're not class- and level-based:
Exalted (no problem to crank it up to really epic levels)
FATE (the fantasy variant is Legends of Anglerre, but if GURPS is a contender, you could also try out the generic FATE iteration called Strands of FATE)
A system i like for fantasy is Roll&Keep, there are two versions for it:
7th Sea (swashbuckling pseudo-europe setting)
and
L5R (fantasy version of a mix of Japan/Korea/China)
7th Sea is OOP but i am sure you could find copies secondhand or go to drivethru to buy electronic copies.
