I'm about to purchase a pair of Creative Aurvana lives, but I also saw this: http://www.amazon.com/ASUS-XONAR-Headphone-Audio-Card/dp/B0045JHJSS/ref=lh_ni_t_dup_mi?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
Would this be worth purchasing also, it is $16 after rebate. Currently I am just using onboard realtek HD. I will be using these for mostly PC gaming and listening to music.
Would I notice much of a difference with the sound vs onboard?
Thanks for the help, Jordan.
