Hm, I don't know the recent exchange rate, but are you sure this is the same card? I paid something like 80,-€ (excl. VAT).

I guess the version of the card I have here was actually intended to be used in some kind of special Supermirco-Extension Slot. However, it fits into a standard PCIe slot and works nicely there as far as I can tell. Do you have the opportunity of using a riser card that would give you one more slot? cu Gerrit
