1 out of 5 eggsWon't Fit

Pros: Works

Cons: If you have a quality case it won't let you plug in to the ports. It is spaced wrong in my Cooler Master case.

Other Thoughts: Should of bought a horizontal slot card. Vertical won't work in 3 cases I have.

2 out of 5 eggsNice Card Bad Drivers

Pros: Fast card with good spacing on USB Ports. Once loaded it works properly.

Cons: Drivers for this card are not automatically recognized. This card is NOT identified in device manager. Unless you load the drivers specifically for this card it will NOT FUNCTION PROPERLY. The drivers will show as loaded but will NOT work unless you get this driver loaded (Windows will show that the correct driver is loaded)

The card does NOT any any identification showing as to who made it!

Other Thoughts: If you get the card be SURE to save the driver.
