I bought an older HP desktop recently for cheap. But I'm not sure how it uses integrated graphics.
It has a gig of RAM and here's the motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00361570&lc=en&cc=us&dlc=en&product=460075&os=228
As you can see, it has three PCI-Standard slots free so does that mean I could see an improvement in graphics (if I did decide to play any older games on it) if I bought a cheap 64MB PCI video card, too? Or is it not worth the effort?
