Which Video card to use with 7N400 Pro 2 rev 2

Archived from groups: alt.comp.periphs.mainboard.gigabyte (More info?)

suggestions?? i use my system for all different things from general
use to gaming to digital photo editing.

i use a giga-byte motherboard based on the Nvidia chipset...should i
consider switching to an Nvidia based video card for better
compatibility or does it really matter?? i currently use an ATI card.

if i switch to Nvidia based...what brand? i have used PNY in the
past...i liked the card a lot.

considering:

PNY Verto 6800 GT 256MB (what does the GT stand for??)

or

PNY Verto 6800 128MB??

suggestions??

thanks in advance!
