I must say you have really good specs but you have to much ram for this graphics. But you can excpect a lot! If you want more i recomend hd7990 because of the ram. But you can be sadisfied with it.

See other videos with lower graphics and ram. Then think.
I know a lot about this things and i recomend hd 7870 its better especially xfx.
R7 is in a range with gtx 650 1gb which im planing to buy but if you have more money buy the xfx radeon.
I want some good quality skin from WTCC 2014.
If anyone can make me the c-elysee skin with number 11, or Tom Coronel skin with also number 11. If anyone can make both or just one skin im apreciate to him and THANKS!!
