Performance in Third-Person 3D Shooters
Just Cause 2
Just Cause 2 reveals the downsides of the multi-GPU configuration. The GeForce GTX 550 Ti SLI is only 20 to 30% faster than the single such card and falls behind the GeForce GTX 560 Ti, let alone the more advanced solutions.
On the other hand, this test highlights the benefits of the pre-overclocked Zotac card which stays halfway between the single GeForce GTX 550 Ti and the SLI tandem.
Lost Planet 2
We’ve got an interesting picture here. The SLI scalability is quite high at 60-70%, yet this only helps our SLI tandem match the GeForce GTX 560 Ti.
The single card from Zotac is close to the Radeon HD 6950 at 1600x900 but falls behind at the higher resolutions.
Performance in RPG
Dragon Age II
Dragon Age IIhas been included into our list of tests but recently, yet the ForceWare driver can effectively parallel computations between the two GPUs of our SLI configuration. On the other hand, the game is obviously optimized for AMD solutions, so the Radeon HD 6950 is unrivalled. As for the GeForce GTX 550 Ti SLI, it shares second place with the GeForce GTX 570 at low resolutions and loses its ground in the higher display modes.
As we saw in earlier reviews, Dragon Age II does not differentiate between GeForce GTX 550 Ti and 560 Ti. Therefore the Zotac GeForce GTX 550 Ti AMP! Edition leaves the 560 Ti behind despite their considerable architectural differences.
Mass Effect 2
We enforced full-screen antialiasing using the method described in our special Mass Effect 2 review.
We’ve got record-breaking scalability of SLI in this test even though it can only be really necessary for nonstandard highest-resolution panoramic display modes. The GeForce GTX 550 Ti SLI tandem easily beats every opponent and allows playing this space odyssey comfortably at the highest resolution of 2560x1600.
The 10% increase in speed the Zotac card enjoys thanks to its pre-overclocked frequencies doesn’t help it reach the level of the GeForce GTX 560 Ti.
