Man, Asus is really going nuts with USB 3.0 gear this week. First a 3.0 compatible motherboard, now this SuperSpeed ready PCI-E card that won't even break the bank at $30.
Unfortunately, the guys at Maximum PC didn't have any USB 3.0 devices to run the card through it's paces. All we know is that Windows 7 boots fine while once it's installed, and it gets similar USB 2.0 transfer rates to other controllers out there.
That said, we all know that USB 3.0 is going to be blazing. As long as the card performs anywhere near as fast as we expect from USB 3.0, the fact that it'll be out "soon" and won't cost much is good enough for me. [Maximum PC via CrunchGear]
