I was excited about testing the HD 4890 in Crossfire and the main reason for that was because I thought it would give us a glimpse into what could possibly be the HD 4890 X2. We know the HD 4890 isn't the fastest single GPU card on the market and we also know that in the performance side of things it sits around the GTX 260 216SP; sometimes better, sometimes worse.
With the GTX 295 ultimately being nothing more than a pair of GTX 260s on a single PCI Express slot, we could really find out today that if ATI merged these two cards together, they may possibly have the fastest VGA card on the market.
What you have to remember is that having the fastest VGA card sells graphics cards. People look at your top product to determine if they should buy from your line. While for the most part ATI represents better value for money, people see that two cards from NVIDIA (GTX 285 and GTX 295) perform better than ATIs top card and simply choose to go the green team even when opting for a lower performing model.
