Only 16 and in college
. I have a friend who is 16 and in college, he's pretty smart, but not that much more than me and my friends (we're the nerds
), just he's the only one who tried to get into college early.
Back on topic: We really need to know what it is you want. A complete overhaul? A cheap upgrade? Are you into hardcore gaming? If you don't mind low settings, you could get away with that with 512MB more RAM and a bigger monitor.
How much $$$ are you willing to put into this. I would't put too much money into your current rig, only some cheap RAM or a new monitor which can be used in a future machine.
