May I ask what mounting equipment you are using? Is it the screws into the base at the very edges? I ask as I bought mine AGES and AGES ago, before the X1000s and 2900s appeared, so I am unsure whether there was a second revision or such to allow mounting on those cards, or whether it needed it. Anyone know? I wouldn't mind recycling my block for a HD4870 myself. Although I would like to know how the D-Tek Fuzion GFX2 performs anyway.
