jaquith, you are correct. I did not specify but I meant standard SB. Was thinking I could use this MB for a mid-level SB now and by mid-2012 upgrade to IB.
Good answers, I will now have to determine what PSU(s) are needed to run this amp hog!
The Revolution looks to have a design for just such a set-up.
nikorr, the spacing of the slots does not look wide enough to allow for the 4th card, physically.
Am I missing something in the picture?
Regarding the PSU or PSU(s) the newer nVidia's e.g. getting the Quadro vibe or FirePro are more efficient and you might get by with a single large PSU.
Here's an excellent PSU sizer -> http://www.thermaltake.outervision.com/ IMO for Rendering use: 1. 100% TDP, 2. 100% System Load, and 35% Capacitor Aging next if it's on 7/24 then look at Gold or Platinum certified.
If you post: 1. CPU OC, 2. HDD(s) number, 3. GPUs, 4. other connected doodads I'll be happy to suggest a couple PSU's or Dual PSU's...
Still putting the list together won't be for rendering. Mostly a folding farm to begin. The GPUs will probably be something along the lines of GTX560Ti. The SB will probably be a i5-2500k only minimum OC'd on air for now. Minimum 8GB ram. Only one SSD, Crucial M4 64GB. These pieces will be gradually doled out to other new family PCs because several members need upgrading. The setup will probably start out with no case, sitting in a cold basement room.
IF you use it for more than folding then don't get the GTX 560's -- IF you SLI (ever) they're limited to 2-WAY whereas the GTX 570 can 3-WAY on a LGA 1155 (4-WAY on LGA 1366/LGA 2011) if the MOBO's also have the 3/4-WAY BIOS Key from nVidia.
I am NOT a Folding guru -- to most that do I'm more noob myself. I have seen a few Folding rigs with several GTX 560's.
