Tell him not to get the X-Fi Fatal!ty FPS. The 64MB of XRAM doesn't give you any noticable performance increase. May-be 1-2 FPS. But with that system, at the high FPS's you'll already be getting, you won't see the extra 1 to 2 FPS. Also the Frontpanel control thing is useless. I've used mine like twice in 3 months.
Tell hime to just get the X-fi xtrememusic. It's like $140 less with out frontpanel and XRAM. And it is 24 times more powerful then the Audigy 2 ZS.
