I am debating on upgrading my Dell XPS 7100 video card. HAs 16GB mem and AMD quad processors. Currently has Radeon HD 5670. Would a upgrade be worthwhile? and if so what would be my best option. Thx for the help.
How good a graphics card you can use will depend on your power supply.
I might suggest a GTX750/ti which will run on most psu's since it does not need a aux 6 pin power connector.
