Hello, I'm currently trying to help a friend build a video editing machine. He was initially set on buying a $2,500 iMac but I convinced him that his money would go further building his own rig. His one caveat though is that he has Thunderbolt, which I see are available on certain motherboards. Anyway, the part I'm most confused about is selecting a graphics card. Initially I thought that running a pair of GTX 770s would get him the most bang for his buck, but have since read that SLI doesn't really work well with video editing. Is this the case? I'm now looking at a GTX 780 Classified as it's supposedly just as powerful as the Titan, but more affordable. Any other suggestions would be greatly appreciated.
