Hello all. I need to upgrade my graphics card in my optiplex 755 small form factor running Windows XP, as it is not cutting it for the games I want to play. I have a tiny budget of at maximum £30 but I would be upset to see that amount of money go. Of course because it’s sff I have a tiny space to work with. I intend to buy used and get something better than a gt 730. I am also getting a Core2duo e8500 for reference so as not to bottleneck either. Thanks in advance!
