My GF is looking to buy a computer, she's found one she can get built online which includes a AMD Phenom II 955 x4 processor and a ATI Radeon 6870 graphics card. the computer comes to £400 roughly with everything else needed (Except monitor/mouse/keyboard ect) and we were just wondering if how this will run games such as Aion which she is currently playing. She cant afford to spend any more than 400
