Hello people, the questions are rather simple, but I prefer to ask you for your expertise on these matters. I intend to get an HD 5970, and watercool it, now: Im undecided yet on wether to get the EK-FC5970 or the Danger Den DD-5970, nontheless, wichever I get, I would like (when possible) to crossfire them - so.... Are both blocks compatible with the EK watercool Watercool HEATKILLER GPU-X² ??? And the second one: Is there somewhere available to buy a SINGLE PCI bracket for the HD 5970 ??? If I water cool there's no point really on keeping the double PCI profile, and would love to get the extra PCI-E lane that otherwise would get blocked by the bracket. Thanks in advance.
