I would suggest that you buy MSI motherboard.I already tested all motherboards posted above for AMD and INtel but i never tested EVGA. ASUS has fully feature, good BIOS (sometimes not stable,upgrading bios from vendors usually untested and bugged) and very high price too. GiGABYTE more stable than ASUS with DUAL BIOS and Green Power feature, good performance but still higher price than MSI. MSI is the best motherboard I've ever seen, stable,low price, very high performance, DRMOS feature that can handle overvoltage.if you feel to overclocking, MSI it's the best motherboard for overclock with no overheating. If you prefer to playing game like Crysis.I suggested that you choose Nvidia than ATI for some reason. and i have no idea for Fallout3 or Fallout New Vegas. Since the games using an old game engines.
