I just got an X-Fi XtremeGamer from Newegg on Monday, after seeing TR's Deal of the Day, of course. I thought I'd take a few pics of it for anyone interested.
I can confirm that the XtremeGamer uses the same Cirrus Logic CS4382 DAC and Wolfson WM8775 ADC as the rest of the X-Fi lineup (except for the Elite Pro). The op-amps look different, though.
Haven't had a chance to install it yet. The computer that it's going in has a HDD problem preventing it from loading Windows.
