Has anyone heard of this X-Fi card?

That's the Xtreme Gamer that came in OEM Machines (IE: Dell, HP, Alienware, ect.)

that used to be my old sound card iirc from my old Dell

Is it a good card? Or did I just get a bad deal.

it's a great card, it's definitely a step up over the current xtreme gamer cards because that has optical in/out and the extra channel input over the current model. in terms of technical specifications pretty much all of the x-fi cards are "same ****, different name". the differences are minute and pretty negligible.

Same as extreme gamer. Just a bit bigger and a few bells and whistles added

pretty nice upgrade from onboard imo

I think the price is so low because they are refurbished sound cards. Not sure what you had before this card but I'm sure it'll sound better.

I have the fatality version of this card and it's an amazing card! If you've never had a X-Fi card before you'll be extremely impressed.
