I went through the same experience with my laptop, where heat built up, causing the thermal protection to kick in and shutting down this notebook. My wife had similar experiences recently, but that was caused by one of our cats finding the keyboard a nice warm place to lie down.
For the once-in-a-while occasional use of the MC or PR, I would weigh the features more heavily than the CPU speed, but of course that is very personal.
Go look and see where a similar computer sits in the rankings
From the little reading I've done in that area (not an expert, could be wrong) I think the i3 is "about" the same power as the Pentium 4 I stopped using almost a year ago
I edited ONLY SD video (DV AVI digitized via Pinnacle Dv500 card) with that computer... with 2 hard drives... and while it was slow (took Encore CS3 overnight to encode and create an ISO to later burn to disc) it did work
You will struggle with only 1 hard drive (an external eSata drive will help) but editing SD video will be, slowly, possible
If you try and edit HD video... I have no idea
Trying to use only ONE Hard Drive for Video Editing
You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to
various parts of the hard drive to do Windows housekeeping or to load program segments for various functions
Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a
fiddle... this would be doing something with your video file at the same time as all the other work
You as a person cannot do both at the same time with the same hand
A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for easy
One hard drive is not as good as two which is not as good as three
Thanks for the input, guys... According to ppbm4 and ppbm5, nobody's using an i3 out there, so I suppose I can expand the data points for ppbm5 by running the test when I eventually get the laptop. Looking back at the i5 machine in my price range, I saw that it was an Acer, which I'm not keen on... I've loved the support I've received with my HP, and read lots of horror stories with Acers. I also would able to utilize my current power supply with a new HP, allowing me to keep one in the office and one at home, which would be wonderful.
I remembered the last time I used PrPro on my laptop--it was to create a slideshow for my wife's grandfather's funeral, a little over a year ago... If my laptop had firewire, I'd probably be tempted to use OnLocation frequently, but without firewire I'm unable to do that, and I've yet to find firewire integrated in ANY laptop even close to my price range. So, I'll be going with the i3. I had done some research as well into the i3 vs. the Pentium T4500 or the AMD P340, and I'm seeing that the i3 is beating both of them quite handily, making it the best bang-for-my-buck in my price range.
Though I'll probably never have to edit HD video on my laptop, I'll do a little bit of it and also run the ppbm5 test when I get it and report back my results.
