I really wouldn't bother with the 1GB version of the 7850. Try to spend a little more to get the 2GB version. More and more games are coming out with high res texture packs which will use more than 1GB of Video RAM Skyrim is one of those games, it will use 1.5GB of Video RAM with high res textures and ultra settings at 1080p. It will use even more if you start adding in certain mods. With additional high res textures I have Skyrim using nearly all 2GB of RAM on my 7870.
