i bought an hp a6300f back in march. it's not exactly the fastest and greatest pc out there, but it was what i could afford at the time. now i am thinking of upgrading a few things in it to try and get a little power out of it. as it stands right now, i mostly play music and the grand theft auto series on it, with the exception of san andreas. i'm not very updated on my games, i know... but what i am looking at doing is getting some games like half life 2 and grand theft auto 4 (when it comes out for pc).
so my question is, what are some things i can upgrade for better gameplay? my budget is probably going to be in the <$500 range...
