Recommendation for Video Cards

[nakpipe]

Sorry, I was having some log-in issues and had to re-register in order to get back on the Forum (no PC luck lately)....... Thank you both Moderators, for the advice. As to "stay away from Intel graphic cards", - - well - - they came when I bought the computer (no choice at this point). However, it sounds like the Nvidia Card would work and also avoid problems with my existing Card.

Can I add a Nvidia Card to one of my open PCI ExpressR x16 slot or the PCI ExpressR x1 slot, and dedicate it's use for graphics? Can you recommend a specific model Nvidia and Power Supply? - - It would be a HUGE help as I am clueless on this! - Thanks again.
