I found out this on POEM. I think it's usefull to have some figures on every GPU/OS:

Whis this project would have something like this... if possible. Think should't be too complicated with all the database info.

Already exists, http://www.gpugrid.net/gpu_list.php

Should also be useful, http://www.gpugrid.net/forum_thread.php?id=2507

:( I'm sorry I didn't saw it

Is it possible that it ranks?
on Linux(1.000) GeForce GTX 275
on Windows (0.492) GeForce GTX 275

Is it due to be an average of people's cards? or due to the drivers on both systems?

If it's an average and standard deviation, maybe interesenting know how many of each because may be affected by overclockers

The Windows table is a reasonable fair reflection of GPU performance, though you would need to double the rank of the GTX590, as it has 2 GPU's. The Linux list looks like a mess. Don't go by it. I don't know how the list is generated but I guess short tasks vs long and different credit systems might have impacted on this significantly. It may also be the case that only a couple of GTX275's were used and only for long tasks, while most people ran a mix, some has bad settings, and the few top Fermi users mostly or exclusively run short tasks. Perhaps down-clocking has played a part too.
