I be skeptical that this would work after have be down the road of update a old computer and run into incompatibility issue at every turn . nothing could have be easier - just put in the card and off and run right away -lrb- after a few software update -rrb- . I migrate from xp to win 7 on a IBM NetVista PC . as other have state on here , make sure you meet the 300W minimum power supply - luckily I have a 400w supply on hand . this do work with Windows 7 even though I find conflict information here and elsewhere .
