Hey. i recdently built a budget gaming PC. i have an amd athlon x4 760k ( the newer richland based version of the 750k mentioned for good budget cpu at around £65) and i am wondering what GPU i can pair with it. it is a quad core so i would think of it to be quite capable ( though not as capable as an intel quad core) currently i have an XFX radeon Hd7770 and i am more than happy. im just wondering for in the future what would be good? i heard i could support a 760 with my CPu at 4.5ghz ( which i have tested and stable) or a 7950 from AMD. Thanks
