I have a budget of about £130 for a cpu. This will be used in a system for gaming. I was looking at the x4 955 as it seems like good value and can be overclocked to 3.8ghz very easily. Would buying a second hand i7 processor be a good option? I know that the 1156 is dead tech so to speak but I'm not really bothered as I plan to keep this system for 3-4 years and the next time I upgrade I'll probably buy a new motherboard. So for that price range what would the best option be? I know sb is great value but if I was to buy that, I would have to skimp on the graphics card. Realistically how long would a overclockec 955 or i7 last for gaming if paired with a gtx 480?
