considering how much juice it pulls, those numbers are not anything to be impressed by... a 5870 has about 2.5flops, this machine has 4 cards and 1tflop
that's pretty stupendously craptacular if you ask me.
mrddr6 let me put it this way. Can it run crysis in dx10 on all very high at 2560 x 1600 with 16xQ AA and still score an average of 60 fps or higher? They are talking about a system that can pull 60 fps on ANY settings with even the largest size monitors we have. Although his math is way off, it's 3.3 TF not 1.1, check your math. Although I find it silly to talk about crysis on a system like this, one that is clearly designed for professional/business use not gaming. Why would you use tesla and quadro for gaming! You should be using this as a render farm/simulator (physics, ray tracing, etc.).
This really isn't anything new. People have been building setups like this with Asus' P6T7 WS SuperComputer motherboard and ASRock's X58 SuperComputer board.
My rough calculations tell me that the components cost around $10,000 per machine. I expect they're using Linux and since Linux and OpenCL are either open source or free so those costs are relatively minimal. Assuming electricity costs of 12 cents per kWh and assuming this machine's PSU is kept maxxed out 50% of the time for five years constantly (pretty reasonable for a departmental supercomputer imo) then that'd be about $3000. So all in all, if their "5 year costs" include electricity then this is a pretty good deal.
