For a brief time yesterday, we noticed that Newegg had the MSI Radeon HD 7990 (R7990-6GD5) dual-GPU graphics card on sale for $550 after a $30 rebate card. The price has since gone back up to $890, but there are still a few deals to be found, and perhaps more on the way. That's pretty impressive when you consider these cards were hovering around $1,000 just a little while ago.
While the MSI deal seems to have expired (doesn't hurt to keep checking), the next lowest price is for a VisionTek card. The VisionTek Radeon HD 7990 is going for $600 with free shipping and no rebates to play around with. There are a few others around the same price (and even a little less after rebate), all of which come with free games as part of AMD's Never Settle promotion.
