Is a graphics card worth it?

I'm running bigbox on an old Dell 790 Optiplex.  Would a new graphics card speed things up?  The mame games themselves run fine, but the videos within the themes are a bit laggy.

A video card would help but you don't need anything fancy or expensive. All you would need is something that fits in your case and has 1 gig of DDR5 vram.

Great, thanks for the advice!
