I currently have an intel core 2 duo e 6750 2.66ghz. Gpu is geforce gtx 260. 6gb ddr3 ram (can go to 8gb). Was gutted when I spent hours loading cod ghosts with upgrades (which take for ever on steam) to find my gpu does not support dx11 even though I have it installed. Need to upgrade but on a budget. Have read about bottle necking with some cards with this cpu. Any ideas - budget has to be under £100 and want to play gta 5 and watch dogs is this possible?
