You need to compare that to an M1710, not another E1705, in order to see if it is an issue of power allotment. And you're sure you have SpeedStep turned off? You really need to run those tests again when you get that 7900GS.
My first thought is yes, the CPU may be throttling down due to the GPU sucking up the power, however when i force the ALWAYS ON in power management, everything works like it used to with no ill effects or symptoms of power starvation, although i have done it for a very extended period of time. Speedstepping is enabled in BIOS. when it is disabled, it runs it at the lowest setting all the time no matter what is set in windows (or so im told), so i just left speedstepping on. I think i need to compare it to an E1705 with 7900gs, E1705 with 7900gtx, and m1710 with 7900gs, and m1710 with 7900gtx, along with the amperage draws for complete data, however i dont have any resources available for an m1710. Hopefully though the 7900gs will be here sometime this week, although im worried the 7900gtx caused some type of permanent change and iw ill see the same results with the 7900gs that werent there before.
The only other thing i can think of is some sort of glitch or error in the speedstepping software, but even then i think it would have presented itself much earlier. If it were a component on the motherboard being overstressed from either an under or over voltage due to the bios not drawing enough power, i wouldnt expect it to sitll work when using another application to throttle the CPU.
One thing i am certain of, it was working fine one day, and the next day it was acting funny.
