BattleForge is one more real-time strategy, but it is more indifferent to the speed of the platform than Warhammer 40 000: Dawn of War II. For the single Radeon HD 5870, any of the three tested CPUs suffices. For two graphics cards, there is but a small difference in the low-quality test mode. There is no difference as soon as you turn on full-screen antialiasing and anisotropic filtering.
The last real-time strategy on my list is Stormrise. It produces the same results as BattleForge but we can see some growth of the bottom frame rate.

Once again the single Radeon HD 5870 does not really need an advanced CPU. The Intel Core 2 Duo at the reduced frequency of 2.67GHz is the only CPU to lag behind the others in the low-quality test mode. But at 3.4GHz this CPU does not limit the performance of today’s fastest single-chip graphics card. The Radeon HD 5870 CrossFireX tandem depends on the CPU in the low-quality test mode. Take note that the quad-core CPUs perform well here: the AMD Phenom II X4 at 2.67GHz equals the Intel Core 2 Duo at 4.1GHz. The Intel Core i7 at 2.67GHz is not slower than the Phenom II X4 at 4.1GHz. But when we turn on full-screen antialiasing and anisotropic filtering, the graphics subsystems don’t depend on the CPU and the frame rate is limited by the capacity of the CrossFireX tandem.
