I know i will need a good graphics card but i am not sure which one to buy.

Answer 1

Stick with the i5 because its better for gaming

Answer 2

the bottom one for £635.96 add the videocard HD6850 for £53.33 its a much better card over the HD5450



Intel i5 is much better for gaming vs the AM3 bulldozer and you save a little money. however the only game title that CPU intensive is battlefield 3 as the CPU does the light shading (no idea why). I am running an AMD dual core 2.0 Ghz and max out Starcraft, Diablo 3, and Syndicate (last 3 titles i bought) at 55+ FPS good luck.

Answer 3

They're bad prices, check out http://www.alame-computers.co.uk for much better prices, these prices really surprised me
