I am getting a graphics card for my friend, and he has a budget of 170 at most. So I've been doing some research on eBay and found a 780 ti for only $120. The catch is that the seller states that I cannot update the drivers, but the card works and video output is displayed. The card cannot update the drivers on NVIDIA's website. Question is, though, is it possible that the card could work fine in another computer? The seller hasn't stated that it was tested on another computer. If the card is toast, could you give me any ideas for a better graphics card at a budget of around $170? He wants to run games like Hunt Showdown and COD WW2 at medium settings with 50 fps (I know, a little stingy for $170 but he is stubborn )
