And now we get to use it on certain boards only: http://www.gigabyte.com/MicroSite/278/touch-bios.html
Now it's available also on H61/P61 platform too, not only on Z68 like it was from the very beginning. You need to upgrade the bios to at least below mentioned version:
H61M-USB3-B3 (Rev. 1.1) F8D
H61M-D2-B3 (Rev. 1.1) F7C
H61M-S2V-B3 (Rev. 1.1) F5E
H61M-S2P-B3 (Rev. 1.1)* F2B
H61M-S2-B3 (Rev. 1.0) F2F
P61-USB3-B3 (Rev. 1.1) F8B
P61-DS3-B3 (Rev. 1.1) F3A
P61-S3-B3 (Rev. 1.0) F4A
