Despite that both the VolariDUO and Volari V8 cards have been for sale in the retail market, not much XGI cards are around. I found this Volari V8 on a Dutch auction website long time ago and bought it immediately. The seller indicated that the card was from a friend who reviewed/tested graphic cards. Take a good look at this card and notice the little white sticker. All the review-cards (and lot's of product on CeBIT for example) have these stickers.

For more information about XGI see the Club3D VolariDUO V8 Ultra page.
