Don't go for dual GPU setup. Buying a single one has its own pros, but with dual it's fine too since they tend to be more better and faster than a single GPU but upgrading them is really costly, they will take more power, temperature issues (but that could be solved with coolers), CrossFire/SLI not supported by few of the games and if they're capable of running the game, either they will run choppy or really great on dual GPU setup.
