Performance in Strategies
Nvidia’s top-end products with the Fermi architecture have always been good in BattleForge, especially in terms of bottom speed. The GeForce GTX 570 SLI tandem carries this tradition on, winning the test. It doesn't open new opportunities for gamers, though. The game is playable at 2560x1600 even on a single GeForce GTX 570, let alone a GTX 580.

The Radeon HD 5970 is quite competitive here. The GeForce GTX 570 SLI is somewhat faster at high resolutions, but the cost of this solution can hardly justify the performance benefits. If you want maximum performance whatever the price, you should wait a little for the next generation of dual-processor products from AMD and Nvidia. Other gamers are going to be perfectly satisfied with the GeForce GTX 580 which can easily cope with most games at highest resolutions.
