*Oh no, not this guy again!* I'm getting ever closer to building the multi GPU folding rig of my dreams, but it's been so long since I dreamed up this monster that I have forgotten some of the fundamentals that I learned from the likes of JackOfAll, coolamasta & saspro back then regarding multiple GPUs in the same board. What I need to know right now is: - Will having two reduced speed PCI-E slots (8x) reduce the PPD that multi GPU cards will be able to produce? - What is the maximum number of GPU clients that you can run under windows with the current client version? i.e. will I be able to fully utilize 3x GTX 295's if I go for that option? - On a side note (and this is really only aimed at those who currently run 295's under water) what are the chances that a 120x360mm HWlabs BIGT radiator would keep two or possibly three 295's cool enough to fold? Thanks in advance. I may change the title of this thread to "Uni's GPU2 Monster discussion" if I have any more questions regarding the specifics of the folding clients etc.
