Currently using on board graphics. However I'm still not experiencing the performance I need. I would like to upgrade this PC so I am able to play certain games such as BioShock or Sims 3 and Black And White 2. I know this a lot to ask of my little machine as it is so old it doesnt even have a AGP slot! If needed I'm willing to upgrade the motherboard.But I'd prefer not to. The form factor is Micro ATX I believe. I want to spend under £200. Ideally I would like the best PCI graphics card and the highest CPU supported. But only if this will allow me to play high spec games. Otherwise I guess I have to upgrade the mobo. Help me Obi Wan Kenobi, you're my only hope.
