I was thinking of getting a new desktop computer, either pre-built or assemble something myself. My primary driver is to have a dual screen setup which my withering current desktop would need a rather large upgrade to support, so I thought, why not just get a whole new system. The trouble is, I'm rather out of touch with hardware, so I don't know what sort of components to look for, so I'd be grateful for any recommendations. In particular, I'd like any recommendations for the video card. I believe nearly any one these days will do for dual screens, but I'd like a decent one. I'll be sticking Ubuntu on it, if that makes any difference to compatibility.
Any help or advice would much appericated, thanks.
