I have $200 to spend on a GPU. I plan on selling my 6870 to buy a 7850, but I don't really know how it compares to other cards. I use my computer for gaming and cad work (autocad, ram, sap, inventor, revitt, solidworks). I originally plannedo n buying another 6870, but it just seems better to pick up a better single card than spend the money on crossfire.
