Those should do good in gaming if you get a decent video card. The motherboard, CPU, RAM, and anything else aren't as important as the video card in gaming.
I suggest you get a newer AM3+ motherboard and at least a Radeon 6570. The CPU isn't very important and you could probably get away with pretty much any CPU that costs more than $60.
If you buy a video card that is as fast as or faster than a 6570 then you should be able to game with the Biostar or Asus (Asus is much better but you shouldn't notice a big difference) but they are older parts. Newer parts will last longer (if you don't buy crap) and be more upgradeable with future tech.
