Hello all,\n\nI am trying to get a little bit of extra life out of a Dell XPS420 which I believe has a faulty graphics card (it has begun artifacting quite a lot in almost all games, progressively getting worse until now completely unusable - do you think this is the graphics card, or something worse? A clean install of Windows Vista did not help at all). As far as I can tell, the rest of the PC is in good shape, and is still quite powerful, so it seems a shame to just dump it for parts. \n\nIt currently has a single Radeon HD 3870. Do you think there is any chance of replacing this with a very cheap replacement. I don't intend to spend a lot of money on a good graphics card - something right at the lowest end of the scale will do, especially as the PSU is still stock 375W :eek:\n\nI was having a look at some of these: http:\/\/www.scan.co.uk\/shop\/computer-hardware\/all\/gpu-amd\/radeon-hd-5000-series-pci-e\n\nDo you think any of these would work? I don't know very much about hardware. \n\nThank you very much.
