Would this be worth upgrading?
One of my friends was getting rid of some stuff, so they gave me two old computers and a monitor and a bunch of other stuff for $50. The computers were a eMachines w3080 and an s2482. They said the w3080 didn't work, but all it had was a bunch of viruses that I since cleaned off. As far as I can see, it runs pretty well for doing everything except playing games. The onboard video can't handle any kind of games. My question is, what kind of video card would I even be able to put in this thing, and would it be worth spending like $130 for it? Because I know a $100 here and there adds up quickly and I wouldn't want to end up one day spending a few hundred on it when I could have saved up and built a pretty top end one. The only games I am interested in playing is like Counter Strike:Source, Garry's Mod, and GTA:SA.
