Sapphire x1950 Pro AGP

Sapphire x1950 Pro AGP Review

Introduction

Although PCI-Express has been around for a while now, there are still plenty of people out there that haven’t made the switch yet, and are therefore still using AGP cards. However, there is a problem here as a lot of manufacturers offer very few options for AGP gamers. Fortunately, Sapphire are not a company to let this lot down and have sent us their x1950 Pro AGP to let us see what it can do.
