I'm not that concerned with 200pts of damage in 1 round from Epic level PCs.
But if you're still worried about powergaming in general, here are my 3 big rules:
1) As others have suggested, be very careful about what PrCls you allow. Just because its in print doesn't mean its good for your campaign. A Dragonslayer in a Dragonlance campaign will quickly get out of hand.
2) Treat feats like PrCls. I know I just said it above, but it bears repeating: just because its in print doesn't mean its good for your campaign. If your powergamer favors warrior types, truncate the melee feat trees- eliminate great cleave, whirlwind attack, spring attack, and any 2 weapon fighting skill above improved. Follow analogous rules for ranged combat specialists. Don't let your spellcasters have the higher level item creation feats with which they would arm themselves and partymates with juicy items.
3) Treat Psionics with care. Introducing Psionics can be fun, but if psionic NPCs and Monsters are rare, a psionic PC can be VERY unbalancing.
