HELL YES!
be careful...i'm not sure about the higher-end cards, but i've seen ATI's Xpert 2000 Pro 2d quality, and it's awesome at 1280x1024....i ended up picking up a powered by ATI card from Club3D for a system I built for someone, and ended up running it at 1280x1024 on my monitor, and honestly, it was completely fuzzy...it was atrocious...i emailed them and told them how crappy their components were...
they're definitely cheaper, and it's not merely because they're no-names...or maybe that's why they're no=names...because of the crap components they use to undercut competitors.
luckily my friend only drives a 17" monitor at 1024 w/ that card...needless to say.
i'd personally stay away from all powered by companies except hercules and probably gigabyte.
