The ATI Radeon 5870 is their follow-up to the 4870 and the current single-GPU flagship of the new 5000-series. The 5870 offers a number of improvements over the 4870 in terms of performance, power consumption and features. The most notable new feature is the new "ATI Eyefinity Multi-Display Technology" (Eyefinity), which offers multi-monitor gaming (similar to Surround Gaming from Matrox) on a single graphics card. This review of the 5870 will focus on the Eyefinity feature, and how issues affect Eyefinity users.

What are we talking about? We're talking about playing a non-widescreen game, on a widescreen monitor, without it stretching. For example: Sid Meier's Pirates! does not support widescreen. It will support a resolution of 1600x1200. How do you play it on a 1920x1200, at a 1600x1200 resolution, without stretching? The same thing goes for Warcraft III, or any other game that doesn't support widescreen.
