Bad lighting? Looks like your camera ate that up with no issues. What kinda camera you got?
Those look like 4x 7970s? What block/cooler are you using on that 4th card?
It's a Nikon D90 with the stock 18-105mm lens.
And it's actually 3x 7970s and 1x 7950 in that rig. The cooler is a
Thermaltake Water 2.0 Pro. The other rig has a
Corsair H110 cooling a 7950.
