t5200 vs. t5600 on laptop/cooler -- longer battery life?

I've decided on the HP dv6000t and and am wondering whether to go with the
t5200 or t5600 processor.
I understand the t5200 is a slightly slower -- (lower clocked) and
lower transfer rate -- version of the t5600 judging by the Intel specs.

I'm leaning towards the t5200 for the following reason(s):

-- it would be slightly cooler than the t5600.
I'm not looking for blazing performance i.e., not into gaming etc.
Just looking for decent 64 bit performance ( I'll most likely be dual/triple booting Solaris/Linux/(Windows) in the near future) and am more interested in a cooler (running) laptop and longer battery life than blazing speed.
(Unless I end up sacrificing a lot of performance in the bargain ).

If anyone has either anecdotal evidence or more formal evidence backing
or contradicting above logic , would appreciate it. My searches thus far haven't provided
much info, but then I'm a bit new to the laptop/notebook world.

Thanks!

Theoritically, there should not be a massive difference in either battery runtime or the heat produced by the two processors. However, some people have complained of their higher end processors running slightly warmer. Battery life, however, will not be affected much, only by a few minutes. If all you want is a notebook that can process in 64-bit, when 64-bit programs are released onto the consumer market, then the T5200 should be fine.

 

They should perform almost identically (power consumption & heat generated) because they are *supposed* to use identical voltages.

 

Thanks Zero, Vespoli
for your responses.
I think I'll stick with the t5200
