INTRODUCTION
For a while, the Radeon X800 XT PE was the best ATI-based card you could get. At the end of last year, ATI changed that by releasing the X850 series of cards. Just like the X800 series, the X850 comes in several flavors: Pro, XT, and XT Platinum Edition (in order of least to most horsepower and therefore cost).
Because Sapphire works so closely with ATI, it is a leader in ATI-based cards and is usually one of the first to market with new cards. In this review, I'll be taking a look at the Sapphire Radeon X850 XT PCI Express. Users with AGP motherboards need not despair for this card and Sapphire's other latest are now also available in AGP format as well. This review will only cover the PCI Express version, but you can expect almost the exact same performance from the AGP version since PCI Express doesn't currently usually offer any of an advantage over AGP. Enough chit chat; let's dig into the review of one of Sapphire's top cards.
