well at the moment my laptop is crap and im just looking for something to get me through for the year im totally content with older games like farcry, but i will be upgrading in the next year hopefully a more powerfull gcard. i use my pc for mainly games and music and movies. i also play music and would like to record through my pc. but at this time its usually for games.
overclocking can give you a noticeable bump in performance for little or no extra cash. But it can have its risks and when things go bad they go real bad. its a personal call but if done right overclocking can save you a lot of cash.
