I have a Celeron 2.13GHz CPU that chokes every time I try to play a high resolution video.
I had read an interesting article on how low end hardware could support HD playback
thanks to Nvidia's new drivers. But it looks like my graphics card is not new enough to try this.
Maybe I can get a cheap PCI slot Gforce 8400
. My Motherboard does not have any PCI Express slots so that really limits my choices.
