Hi peoples I am in the uk and upgrading GPU. Not sure what card to get budget is 150.00 GBP I would be very thankful if someone could give me honest feedback and the best for STALKER DX11 My specs are as follow
AMDX2 240 CPU
450 WATT PSU (UPGRADING SO NOT A PROBLEM)
Your CPU is fine unless you plan on running some very high end multi-gpu's. Upgrade that GPU first. I would get a reference HD 5770, stock GTX 460, or the cheapest HD 6850 you can find. I would lean towards the 5770 or 6850 though since they sip much less power. At that resolution, even a GTS 450 or HD 5750 is going to be overkill. Your next upgrade after that GPU really needs to be a high resolution monitor. You might be able to find a used reference HD 5850 for cheap (I'd stick to shopping forums and not ebay).
