Best $120 GPU?????

Solution
Not much better than your HD 7850 but this is the best I found in your price range.

XFX Radeon R7 370 DirectX 12 R7-370P-2SF5 2GB 256-Bit GDDR5 PCI Express 3.0 CrossFireX Support - 119.99

Solution
the new gpu's are coming out at the end of 17' and will start with high-end so probably early 18 for low end ones. i need to upgrade sooner due to my son needing the hd 7850 back in his pc since his other gpu died.
 
also the gtx 950 cheapest ive seen is $150 right now......may be able to get a used 960 in my area for 120 but its not through a licensed seller so im kinda concerned about that
 
the 129 gtx 950 is after rebate so its actually a 140 dollar card. and as ive stated above i can not keep the current card as it is going back to my son since it belongs to him and his other one died. so i am forced to buy a new card and i have $ 120 to do it with not after rebates since i dont have the money to spend and wait 2 months for a rebate.
