Basically, the smaller there manufacturing process is, the more transistors and stuff they can put on a chip making them faster. Plus by having it smaller it requires less energy and produces less heat. 45nm is smaller than 65 nm.
i plan on getting a new processor soon and have a budget of 200pounds, i may experiment on overclocking my current processor i have now, but i want a new one ready for christmas so i will be able to get a rly nice gfx card
thats the thing, im only 14 and dont have 2 clues about overclocking and neither does my older brother, thats why we didnt overclock the processor ive got now
how far do you think ill be able to push my e2180 before i need to change anything other than the FSB? Its currently running around 20-25*C idle and around 30 whilst playing CoD4
