We've already established that buddy.
Anyways. I downloaded the Max Payne demo from the Rockstar Games website. Don't worry it's legal. I installed it and it play rather well. It did slow down a bit sometimes, but not that badly. Also the load times seemed a bit lengthy sometimes. There was one problem though, it slowed my computer and it's ability to connect to the Internet alot. Anyways, if my PC is able to run that, it should run GTA games right? Also, since my drive is broken, is there a way that I can put it in download form? Then I would'nt have any problems getting it on the PC. I'm at the point were I think the only thing I can do to get a PC to play games is to get a better one. This one was abought $500-$600. I'm think about getting a Dell for Christmas. A new Dell with Windows Vista should be capable should'nt it?
I think you could find a way better computer for the price of a Dell, especially if you already have a decent monitor from your current computer. It really depends on what you get, man.
