Hey Bigjme, if I recall correctly, you run a 6x 750ti rig.  I'm looking into building one myself (due to the recent spending money JPC and the rise in BTC has made me ).  I have loads of experience building computers and configuring them.  I'm new to the multi GPU route though, never even bothered with SLI for example.  Is there any advice you'd have for someone new to this, and could you recommend a specific motherboard?  Asus, MSI, Gigabyte, ASrock would all be very ideal as I'm in Taiwan and I'll have cheaper prices on those brands.  I'm also pretty in the dark with risers and all.  I've seen some people say they like usb based risers, and then there are powered, non powered, etc.  I know the 750ti doesn't use a dedicated line from the PSU, so that makes me wonder even further if it's wise to run 6 cards through a mobo.  Last but not least, I know that CPU plays into it all a bit.  my current 750ti micro atx has the celeron haswell g1820.  Lovely little cpu, but I'm just wondering if 4gm of ram and a tiny cpu would be enough for a 6 gpu rig.  Of course I'd like to keep it as economical as possible, but I have absolutely no qualms about getting better parts or specs to prevent future issues.  I currently ran into that on the 750ti micro atx rig not preparing for scalability and all.  Thank you in advance!
