I don't see why not. Most of those boards will still be functional after all and it stands to reason that someone somewhere is going to be getting rid of one. However, it's likely that you'll be upgrading to a whole new graphics card if it's a two year down the line deal. It all depends on how powerful the next generation of gpu's are. If it's a minor bump then go SLI, if it's a major bump then you'll likely get a whole new card.
