That is the brand, but I use the 4 port model. This is exactly the one I purchased.

I don't think the one you found will not work because it does not use the Fresco Logic controller chip which is what is needed for the OS X built-in driver.

What would be good and cheap usb3 card what works in mac pro perfectly?

These all work in ML and are inexpensive:

Fresco Logic FL1009-200
Orico PFU3-202I
Orico PFU3-2P
Orico PFU3-4P

However, they can slow down if you are transferring data on multiple devices at the same time, and they require additional cables. The cables and how to install them are here. You might want to read the whole thread if you have time; there are discussions of pros, cons, and alternatives.

I have the Fresco Logic FL1009-200 but it suffers from improperly ejecting when when waking up from sleep. Does your USB 3.0 card suffer from this issue? Jettison did not solve the problem.

I used to use SMC fan control to keep my PCIe bay at 1300 minimum. I actually added a 120mm fan inside the PCIe bay for more flow. I built an external fan controller for the 120 and keep it at 1100RPM unless I'm gaming, then I crank it to 1800RPM.

One thing that I noticed With my Mac Pro 1,1: I ran dual Radeon 6850's in SLI and it would not even boot all the way to the Windows Desktop without the Fan speeds cranked up. Once I did that, everything was fine.
