I'm pretty sure the hardware layout is the exact same, physically, between the GTX and Ultra.
Softpedia: NVIDIA 8800Ultra Is a Factory Overclocked 8800GTX
In this line of thoughts, we have learned that the 8800Ultra card is just a factory overclocked 8800GTX, featuring 128 stream processors and 768MB GDDR3. Even the PCB is the same, the only major modification will be the cooler, which is bigger, and for those of you who need multiple choices, the card manufacturers have two cooler designs to choose from, therefore, users also have the same two choices to make.
But, saying simply "the 8800Ultra is a factory overclocked 8800GTX" is kind of misleading though, in my opinion. Because the voltage needed for the higher clocks is also higher, and they've increased it with the Ultra - something you'd have to do with a volt mod on the GTX to see overclocks like the Ultra.
Now I'm not to sure about this, but according the GPU Review here
, the shader clock also runs at 1500MHz opposed to 1350MHz with the GTX, and in order to get the shader clock to run at 1500MHz on the GTX, you'd have to OC the GPU to 725MHz, opposed to the Ultra's stock 612MHz. (You have to play around with the advanced options at the site.) GPU Review's specs might not be 100% accurate though.... so someone might have to correct on me on this one.
Overall, I think the Ultra isn't exactly the best "bang for you buck", and IMO really isn't worth the extra cash... but if you can afford it, go for it... it's a blazing fast card.
