Default 64 bit processors

I have an Athlon 64 3000+, once Windows 64 bit comes out, and once I buy it, will Prime95 run faster, or twice as fast, seeing as I'm running @ 64 bits instead of 32?

EDIT: Oh, and something completly unrelated to this subject: when i run P95 on my laptop, the CPU temp hits 172, i know this isn't good, but is there anything I can do to maybe make it use less CPU, or should i just not run it at all on there?

At least not now.
64 bit enhancements will be used somewhen in the future - but this could take months or even a year or two...

There is a 'throttle' function in the latest public versions of Prime95 it sets the number of milliseconds that Prime95 waits until starting the next iteration.

If your iteration time is 150 milliseconds, you could throttle by 50 ms and effectively run Prime95 at 3/4 speed.

It will run ever so slightly faster. Remember prime95 is already 64-bits (floating point numbers are 64-bits). The extra SSE2 registers will help a tiny bit.

Trial factoring will be faster too, up to twice as fast.

Any chance we could get a trial-factoring-only version of Prime95 early?
