The game has modest system requirements indeed. Every graphics card in this category, with the exception of the Radeon HD 4850 X2, easily ensures a comfortable frame rate at a resolution of 1920x1200. The 4800 X2 must be hamstringed by its low GPU frequency. It has a lower bottom speed than the single-processor GeForce GTX 285 as the consequence.
The resolution of 2560x1600 pixels is only playable on the 3-way Radeon HD 4870 CrossFireX subsystem. The GeForce GTX 295 can also be used to play at that resolution, but with occasional slowdowns to below 23fps in the most complex scenes.
Thus, the Radeon HD 4870 X2 and GeForce GTX 295 are both the best dual-processor solutions. The former delivers a higher average frame rate while the latter offers a higher bottom speed which can serve as a reserve for the heaviest scenes of the game. Nvidia’s solution is preferable in terms of consumer properties since it has lower power consumption and heat dissipation, but it is more expensive than ATI’s flagship. The GeForce GTX 285 is the leader among the single-processor cards, leaving no chance to the Radeon HD 4850 X2 if you base your choice of the graphics card on this game.
