Sapphire Toxic Radeon X1900 XTX

Intro, Specifications & Bundle

**Update: Sapphire re-branded this product the Toxic Radon X1900 XTX after our review was published.

Sapphire has been one of ATI's premier board partners for quite some time now. Their products tend to be very similar to those available directly from ATI themselves, but Sapphire does take additional steps to differentiate their offerings with unique accessory and software bundles, and occasionally unique cooling solutions. In the past, we've reviewed a couple of Sapphire's passively cooled "Ultimate Edition" cards and have also evaluated a few products in their "Toxic" family of products that feature oversized air coolers. Today though, we're going to take a look at a Sapphire's first liquid-cooled card, the Toxic Radeon X1900 XTX.

As its name implies, the Sapphire Toxic Radeon X1900 XTX is based upon ATI's latest flagship GPU, but instead of featuring a dual-slot heatsinks / fan assembly like ATI's cards, the Toxic is equipped with a slick, self-contained liquid-cooler that keeps the GPU cool without generating much noise. Sapphire also plans to ship the card pre-overclocked, which will give it a performance advantage over any standard Radeon X1900 XTX that strictly adheres to ATI's reference specifications.

Sapphire's high-end cards have been shipping with a very comprehensive software and accessory bundle as of late. Included with the card itself, we found a basic user's manual, an addendum detailing CrossFire power requirements, a driver CD-ROM, and an assortment of other discs that included copies of Cyberlink's PowerDVD 6, Power Director 4, and Sapphire's "Software Select" CD.  Although it wasn't included in our sample, the Toxic will also ship with a copy of Sapphire's "TRIXX" overclocking utility.  The copy of Cyberlink's Power Director video editing software was included to compliment the card's video in / video out (ViVo) capabilities. In past reviews we've found an older version of Power Director to be quite useful and easy to use (see here).

The Software Select CD is a Sapphire exclusive that gives buyers a choice of their gaming bundle.  Two unlock codes are included with the disk, with which users can install two of four available games, Brothers in Arms (Road to Hill 30), Prince of Persia (Warrior Within), Richard Burns Rally, or Tony Hawk's Underground 2.

There was also a collection of cables and adapters included with Sapphire's Toxic Radeon X1900 XTX. There was a standard 6-ft S-Video cable included, a composite video cable, and two DVI-to-DB15 adapters along with a splitter for connecting the card to an HD-TV's components inputs, and another adapter equipped with S-Video and composite video inputs and outputs. Lastly, there was a molex-to-6-pin PCI Express power cable adapter thrown in as well.
