I have a 2 CPU Dell 6420 with 2 gigs, a fairly old computer. I want to know if this computer will support an external graphics card? Games will not run and DELL techincal support doesn't seem to know if the graphics card is permanently attached. I prefer to purchase an external graphics card at this time. Thanks for your help.
