Bitcoin 7970 hash rate Coins charts hash

NVidia GPU suck for mining, is there anyway around this?

What makes them so bad? Is it the drivers or how the card is built?

New to BitCoin Mining.

Right now my dad has a computer with the following stats:
*Intel i7 3930K Hex Core CPU
*64GB DDR3 System Memory
*ZX5 Dual ATi Eyefinity 7970 GPUs
*240GB Intel 520 Series SSD System Drive + Dual 2TB Automatic Backup Data Drives in RAID 1
I was thinking of investing in a 25 GH/s Bitcoin Miner
So my question is what else would I need for bitcoin mining? How much should I expect power usage to be? and I assume I'd be putting out 25,000 MHash/s...?
I'm real new at this but I'm figuring since I already have a solid CPU rig it wouldn't be too much more of an investment to start earning with bitcoin mining? or am I completely off-base with that?

Remembering that these are Australian prices, how does this build look for a general purpose workstation / folding / gaming rig? It's main goal is for 120FPS on 120Hz monitors in eyefinity (Once you've gone 120Hz you can never go back), and compute (fold/mine) like a mofo, but I also work on it. (Autodesk suite, Premiere, 3DSM, SolidWorks, Inventor and more)
I would have liked to have gone a little further here and there, but I have to draw the line somewhere. To be specific where I would have liked to not cut corners:
The quadfire dilemma I had not originally planned to go for quad 7970s, the aim was just trifire to push me near that 120FPS for eyefinity, well beyond in the most intensive games for a single monitor and reduce microstuttering. I did not like the idea of the cards trying to peel hot air off the PCB on its sibling card like they were suffocating and suffering from asthma, so I planned on using an Asus Rampage IV Extreme, using slots one, four and seven to allow a one expansion slot gap between each card, in a Raven RV02 (non evo). Then my buddy (who also does Bitcoin mining) pointed out that if I kept the gigabyte board I would only spending an additional $0~ to $200~ (depending if I sold the Gigabyte board) by NOT purchasing the much more expensive Asus board and getting a fourth 7970 instead. We worked out the math and the extra card's Mhash/s would pay for itself in two months. Noise and heat aren't a huge issue as it's only temporary until I sort out the water loop. I'll also be getting a bit more gaming performance (when it works) and my general workstation tasks like rendering (V-Ray RT, SW etc.) will also be happy with the extra GPU compute power.
I have a HighGrade triple 24" stand and had to return the monitor I just bought, and am still yet to decide 100% on which displays but I am leaning towards three BenQ XL2420T 24" 120Hz 1080P monitors. Unlike the 120Hz Samsungs, they have VESA mounts and unlike the 120Hz Asus monitors, I'm not paying a premium for Nvidia 3D Vision that I'm not going to use. Really looking for suggestions/recommendations here!
The case The 650D can fit a thin 280 rad in the top & 120 on the rear. With the HDD cage removed, 200 in the front or 240 on the floor, perhaps a combination of both with some modification (though unlikely, I enjoy a challenge). I could make it nice and neat, but I think I still prefer a chiller under my house with lines routed through the floor. Thinking of using a quality 1/4HP or 1/10HP Aquarium chiller for the job (only a couple hundred more than a good radiator setup). I'm still not 100% set on the 650D and open to other case suggestions. I appreciate the functionality of the Switch 810 but I do not like its aesthetics or size at all. Caselabs are too expensive once optioned and shipped to Australia. Very open to suggestions here also.

Why do more expensive GPUs have worse MH/s rates than less expensive GPUs and graphics cards?

For example, on this page of mining hardware from the sidebar, the NVidia Tesla K20 gets 134.8 Mhash/s and costs over $3,000.00, while an ATI 7970 gets 825 Mhash/s and costs about $380.00.
Presumably the NVidia has a higher flop rating than the ATI, so why doesn't the more powerful NVidia have a higher mining rate? Is it that the NVidia simply isn't made for the kind of computing involved in bitcoin mining?
EDIT: The ATI card has the following specs
3.79 TFLOPS Single Precision compute power 947 GFLOPS Double Precision compute power 2048 Stream Processors 
The NVidia Card has the following specs:
CUDA cores 2496 Peak double precision floating point performance 1.17 Tflops Peak single precision floating point performance 3.52 Tflops 
So the Flops are comparable overall, and the NVidia card has more cores. I don't understand how the ATI gets over 6 times the Mhash/s than the Nvidia does.

I'm using a 7970 with CGMiner at intensity of 9 and Core Clock at 1100. I run between 670-700 mhash/sec. I'd recommend CGMiner if I were you. Luckily my space has A/C included so I just keep it at 64 degrees F and have no worries about overheating. Runs at right around 80 C. My last 24 hour average was 660 Mhash/sec.
