Retail boxes on both, but might not have DVI-VGA adapters. I am original owner of both cards and they are about 2 years old, folding@home 24/7 until about a month or two ago (cards work perfectly, stopped folding because my Win7 evaluation copy expired and I haven't had time to re-install an OS...). No factory warrany on the PNY (at least none that I know of). XFX is registered, so warranty should be transferrable.
