Listen to this guy. ^ And also, if you can want, you can hold off until around Q2 of next year when AMD release their new 8000 series. Which are better and will most probably be cheaper. Main reason I'm holding off my build. Also Amazon are usually cheap for components. I saw the i5 for £145 the other week. And do you want to overclock? Edit: You could also go for a 7950. http://www.amazon.co.uk/Sapphire-11196-09-40G-HD7950-Vapox-X-Graphics/dp/B0091MFBZC/ref=sr_1_1?s=computers&ie=UTF8&qid=1355834453&sr=1-1 The 660ti is slightly better, but there is more overclocking power in the 7950. All depends on whether or not you want to OC. You would also need a higher wattage PSU for OC'ing. And again for OC'ing, a i5 3750k would be better as it has a better stock GHz...
