And yeah one more thing is 2 Go GDDR5 SDRAM Good?

Yes, its ok, but 16GB were a better solution for you. Also the other components needs to support the Heartbeat frequency of 1600MHz. In fact the mainboard and so on. Also you will need a good- really good graphic machine … > nVidia 570 ( absolute lagging minimum).
