Four, five, and six displays with one card; 2GB VRAM.
Not the fastest card for the price; six-monitor gaming is performance-limited.
Do gamers really need six monitors? Having two displays—maybe even three—on your desk certainly makes sense for a productivity boost. And having run some games on three displays, we can say that the added immersion in the game world can indeed be compelling. But you can run three displays with any Radeon HD 5000–series cards, provided you have at least one DisplayPort monitor.
Sapphire and AMD are betting that some gamers will lust after more than three displays, which is why Sapphire is shipping the Radeon HD 5870 Eyefinity Edition. This isn’t just a stock 5870 with six monitor connectors; it also ships with a 2GB GDDR5 frame buffer. So even if you aren’t planning on running six displays on your desk, the 2GB of VRAM might itself be attractive.
