ok I have a Custom build, now my old Radeon HD 7900 has given up the ghost and I'm not sure what to go for, I have a Z97 - P Asus motherboard, intel I5 Quad core 3.20 Processor, 12 Gb Ram and a 650 watt power supply, I have about £200 to play with but don't really know what to go for, I'm not to fussy about AMD or Nvidia .can anyone give me a hint in the right direction?
