Hey guys I currently have an Asus Radeon 7850 HD 2GB 256-Bit GDDR5 but I have a buddy who is selling his Asus GTX 680 4GB GTX 680 4GB 256-Bit GDDR5 for $200. Is it worth it to upgrade? I have no idea how much of a performance boost the new card would be over my current one. Future games I plan on getting are Arkham Knight, GTA V, CoD/Battlefield, WoW Warlords of Draenor (well, all blizz games really), Far Cry 4 and the new Tomb Raider, just to gauge the kinds of games I play (GPU-intensive-wise).
