I've been running both Win XP & Ubuntu 12.04LTS on a dual boot setup (2 separate HDs). System is about 8 years old and has an Intel® Pentium(R) 4 CPU 3.00GHz dual core with 2 Gb RAM and a Nvida GeForce FX5500 graphics card. This card is now too old to support anything newer than Ubuntu 12.04 - I've tried both 12.10 and 13.04 but the graphics response is almost unusably slow. I've also read that MS are stopping support for WinXP in April 2014, so I'll need to upgrade Windows as well as I need it for work related things. I understand that Win 8 probably won't work on this set-up, so the real question is - is it worth getting a new graphics card or will I have to get a whole new PC ?
