I agree, the only significant difference is the bezel (x-ram is unused in a vast majority of games as I understand). However..... getting the bezel for $20 more is pretty nice. That thing costs about $70 bucks to buy as an upgrade, so I consider paying $20 more pretty cool. The main reason I wanted a bezel was so I could plug headphones into the front and have it kill the sound coming out the back (since x-fi does not have an on-card plug for front sound). But if you'll never need that, and have absolutely no use for the Bezel, then yeah, I'd say go cheaper.
To Mati87, THe extremegamer on newegg would be more expensive (1$ more) than the X-Fi Fatal1ty, as I'm pricematching Bestbuy with Circuit City, for a total of 89$....compared to regular for 90$, and Champion for $110.
The Z-5300e are only analog....
But it's the same sound card/chipset/specs for both of them, right?
