Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
Heres the reason why:
ExpressCard bandwidth = 2.5 Gbit/s
8x AGP bandwidth = 2 GB/s
For those who don't know there is 8 bits in a byte. Kids, this should be common computer knowledge. For those who can't do math, 2.5 gbit/s = .3125 GB/s or 320 MB/s. There won't be much or any gains with this if you have even decent dedicated graphics. If this thing does have a 7900gs in there, it won't even come close to what it should in terms of price / performance.
Unless this is priced really reasonably (i.e., between $50 - $120), this won't sell.
