Hi All


We ended up in choosing the 5970 against the latest firestream for its better performance/money ratio. I would like to build a workstation for scientific purposes with 4 card HD 5970 in crossire configuration under Fedora core 12 64bit  and I have some problem to solve in both  hardware and software sides. I hope I will find a the right answer here.



does the most recent linux (64bit) driver spport 8 gpu's?

is there any architecture constrain? (e.g.  max addressable GDDR5 ram, intel vs AMD mobo chipset)


The HD 5970 occupies 2 slot in thickness, hence It would require a motherboard with 4 pci-e 16X double spaced. I'm looking for both a solution with socket 775 and the new socket 1156.

I have the feeling that it is going that the case is going to be very hot, any suggestion?

Fast estimation tells me a need at least 1000W power supply, any suggestion about it?

I know that due to the number of questions this message can be a little off topic, I hope you don't mind if I post it here


Thanks for any help you can provide me
