Introduction

Being an ATI only partner, it's important for Sapphire to have a large array of variations when it comes to their model line-up. Split into four categories, we have our standard reference models from them. Moving up a notch to the Vapor-X line, you get a nice upgraded cooler, but the same reference clocks.

After the Vapor-X you've got the TOXIC variants which are what we have today. They're essentially an overclocked Vapor-X model, so you get the upgraded cooler, but also an upgrade in clock speeds.

In the top spot is the ATOMIC. That series carries with it an upgraded cooler and the best clock speeds that Sapphire can offer. It's been a while since we've seen anything fall under the ATOMIC line-up and we think the main reason for that is the supply issue that companies have had with the 5000 series. Hopefully that will change in the coming months.

Today we've got the TOXIC version of the HD 5850. I like the Vapor-X series because I like the new coolers, but there's just something that bit more fun about an overclocked card, so I'm excited that the HD 5850 has finally got the OC treatment.

Before we have a look at the card itself and its overclock, we'll have a quick look at the spread Sapphire has put together.
