I did a search in the forum looking for current video card reviews, but I couldn't find one, so my question is what is the best video card for the current line of MacPro's? I currently have the ATI Radeon HD2600 that shipped with this Mac, but I'm looking for more power and custom ability! I read so many articles on the web that I'm extremely confused. I wish there was a website that stated the obvious: If you have this mac, these cards will work with your configuration, period! I'd pay for a site like that! Any thoughts anyone?
