[RunnerRon01]

I just purhased an HP Touchsmart 420T and I'd like to know if I can add a video graphics card?

This is the same answer that has been given for every model over the past 3 years and continues to be the case.

For all intent the graphics cards in the Touchsmart desktops are NOT upgradable, even with a "standard" MXM card since the motherboard and BIOS are custom made for HP and do not support additional non-HP graphics cards and their firmware/BIO

I'd like to know why you feel you need a graphics card.  Haven't purchased yet, and have concerns about the integrated graphics.

I have a TS 520-1050 and the graphics is just fine. Sure the card could be a higher rated gaphics but playing games etc I have no issues at all . I have been playing blacklight retribution and system works great. BY the way check it out high rating free  on line MMOFPS.
