I'm planning on getting a new PC with the intention of gaming. I intent to replace the graphics card and the PSU so I can play pretty much anything. A game I've always wanted to play on it is San Andreas for the modding and multiplayer capabilities. I figured since laptops can run it, so should my PC out of the box. The main issue I have is the graphics card. The PC uses an integrated Nvidia 7100 card. Now I as far as I'm aware, there's a spare PCI slot to upgrade the graphics but I won't be able to for a while due to financial constraints.
Here's a link to the PC so you can check out the rest of the specs.
I also heard that there were some issues with compatibility with Windows Vista, does anyone know how well it runs on Windows 7? Thanks in advance for your help.
