The other cards almost copy the reference design in this regard, but have minor differences introduced by their manufacturers. Obviously, only the AFOX product differs from the reference design, having all memory chips on the front side of the PCB.

I have tried installing the driver from pretty much everywhere I could find them and every way I could. It's significantly cheaper than the next card up, AMD's 350 Radeon HD 7950, and its. If I restart my computer my screen will go black when windows starts up. The HD 7870 is the first card we've seen with AMD's new upper-mid-range 28nm 'Pitcairn' graphics processor. The card is installed correctly and there are no other graphics driver on my computer.
Whenever I update the driver on my ATI Radeon HD 5770 all I get is a black screen.
