I was thinking of upgrading my current PC while I wait to get a new PC. My current PC is an HP and only has a 64MB Graphics card, I had this card in mind http://www.globalpc.co.nz/proddetail.asp?prod=VC15052  mainly because it's very cheap. I think my PSU is only 150W, would this be enough to power that card and, is it a good idea to install a cheap graphics card, while waiting for a new PC, or can it be damaging to your system.
