Cryostasis is one of the most poorly optimized games ever. It runs like shit on even the fastest systems. Do not draw any conclusions about your hardware based on Cryostasis! It's a shame because it was a decent game if not for the terrible performance.
The results look lower than I would have expected. Here are my results with three different setups using the system in my sig. I'd suggest running it with the 560ti doing Physx. You might get better results.

I think you are CPU limited. Athlon X3 does not have any L2 cache, and its IPC is pitifully weak, and you're playing at 720p, which is highly CPU limited. If you want a fair comparison to glean some more info, try the benchmark at 1080p instead, and compare it to the results of the person that posted ^^^. That will tell you some more.
As of now I doubt that you are having abnormal behavior, but more research is necessary.
