Diamond Multimedia's Stealth S80
A legend returns to the graphics market

Many seasoned PC enthusiasts fondly recall being the first on the block to have a high-powered Diamond Viper card in their rig, and boasting about it to their friends.  Back then, Diamond and performance were nearly synonymous in the computer world.  It was a big loss when they pulled back in 2001, only offering their Supra line of Modems and Rio MP3 players.  After a three-year absence, however, Diamond has returned, starting off a bit slowly with their new value-minded Stealth line of cards which will soon be followed up by a high-powered Viper line.

Upon hearing of Diamond's resurrection, we had high-hopes for a unique product line.  The only way to stand out from the crowd is to offer something distinctive, whether it be the software bundle, the cooling method, or some other feature such as Tyan's TGM technology.  What will Diamond, or better yet, Best Data bring to the market that will make them a front-runner once again?  See, this is Diamond in name only.  Best Data purchased the rights to Diamond's brand names and trademarks, and is using the Diamond name to make a bigger push into the graphics market.  The big question is then, can Diamond / Best Data re-capture the hearts and wallets of an already jaded buyer's market?  That remains to be seen.  Our reintroduction to Diamond begins with the Stealth S80 - a feisty little card powered by ATi's Radeon 9200SE VPU.

The bundle is just what one would expect, considering the main-selling point of the Stealth S80 is its price.  There's two CDs in the package, one that contained an interesting mix of drivers, software, and benchmarks.  The other CD is a full version of Spy Hunter, a remake of the classic arcade game which should perform well on the Stealth S80.  In what is surely a cost cutting move, what you won't find in the box is a user's manual.  The only paperwork was a quick installation guide, the warranty and registration information, and a voucher for two free issues of PC Gamer.  Diamond also threw in an S-Video cable for connecting your PC to a TV.
