I'm thinking about buying this graphics card. http://www.komplett.co.uk/k/ki.aspx?sku=334545&view=detailed Gainward GeForce 8500GT 256MB DDR2, PCI-Express, DVI/Tv-Out, SilentFX The problem is i'm not great on the hardware side of things and i'm unsure as to whether my system would support. I think my computer is PCI-Express because when I used the crucial system scanner that's what it reccomended, a PCI-Express card that is. I also have this link http://h10025.www1.hp.com/ewfrf/wc/...e=c00587146&cc=uk&lc=en&dlc=en&dlc=en&lang=en which is the product specification of my computer. The only difference is that i'm running Vista and I have 1.5GB of RAM. I don't know how to check my power supply. When I look at the back of my computer it just says 230V and the card requires a 300W power supply. Can anyone help me out? Thanks in advance.
