and I thought the more memory and core you get, the more it will allow you to push the shaders
You can choose any value you want however the nVidia shaders will only go in those increments. An example of this is RivaTuner. I use the G15 tool in Riva to display my system conditions; clocks, temps, speeds, etc and even though I can choose any value, Riva always displays the straps at the 54Mhz increment up or down.
Even tho your setting it to whatever you want, it goes up to the next strap if > 50% to the next or down to the lower strap if < 50%.
There are some threads here about this and it's been confirmed.
As for the core, sure, you can use core/memory to help increase the shaders to the next strap but again doing so adds heat. It's entirely up to you if you want but again, the shaders are only factor in GPU2 folding that give more or less PPD.
