Now what would be the IRST? So I can install W8 with all the W7 drivers that are on the official website of Bloodrage same? Thanks man for your help!
There is no Realtek driver about Xonar STX, you need to download a driver from Asus support site - particular Xonar STX Win 8 driver:

IRST stands for "Intel Rapid Storage Technology" - a set of Intel ICH/PCH drivers (a disk controller):

Again - with Win 8 you do not need W7 drivers that are on the official website of Bloodrage. You may install Win 8, use all built-in drivers supported, and download from manufacturers' sites (like the two links above) only drivers providing additional functionality.
