I am going to buy a Radeon 7850 this christmas and I am just making sure before hand that it would be alright to add to my system the way it is 
My specs are: Motherboard - MS-7641
RAM - 8gb ddr3
PSU - 500w
CPU - amd fx-6100
So with my currents specs, am I good to just go and buy the gpu right now? Thanks in advance
