have a 8x agp 128 MB Nvidia card in older pc -lrb- 5 yr old or so -rrb- and install this card to give the video a lift for more serious gaming . upgrade the CPU a little at the same time , single core Athlon from 2800 + to 3400 + . let the xp `` find hardware '' utility find the driver on the internet . it take a while to locate and install the driver but work flawlessly . beware : Card work ok but end up have to bump up the system memory , card use a lot more than old one and do not leave enough for OS , so video be choppy . have to upgrade from 1 gb to 2 gb , now it work great .
