Hi, Getting a bit confused with all the information out there, my nephew has got a new gaming PC, but he is looking to get a dedicated graphics card for it as he doesn't think the onboard card is any good, here is his set up, can someone please help point him to a decent card for gaming... AMD A8 7600 Quad Core @ 4.20GHz, ATI Radeon HD R7 Graphics (believe this is the onboard card), 8GB DDR3 1600MHz RAM, 1TB HD and Gigabyte A68HM. Any help would be gratefully accepted, Thanks in advance
