Anyone any update on SDK2 integration for Oculus ? Or any other suggestions how to link up Oculus Rift in real time to Octane ?

GTX580 uses around 200-240 watt, so multiply that x 8, plus add some for rest of your PC --> so I would say you prob need 2400 watt . that's 2 x 1200W supplies.
If you use GTX590 you need 240-300W peak ...

I would say the ideal winter project - will save on heating (if you have solar panels ) !

thx - formula is handy to know. Have already done benchmarks with the "star wars tunnel", but looking for more complex scenes for octane to test in short term, like the interiour scene that was used to demo the 8 GPU setup.

Where did you find the PCIe extension cables ? My hardware shop claims it is very fragile.
Has anyone got experience with ...

OK, got the authentication now. Thx !

Nice rig though - did u built it yourself or got someone to assemble it ? Where did you find the Termin case ? Saw the youTube on the new coming 12 case.
Are you in Europe somewhere ? Good to heaqr the GTX580 will stand 4 next to eachother. Have the eVGA GTX590 Classified, and am awaiting my ...

gabrielefx: yep, the 2CPU option in 3 is a Tyan 4U rack I found. rack itself costs 2550 GBP. You need to add cost of GPU's, CPU's and mem. 2xPSU, MBrd and case with vent are already included.
