Thanks to all for the info ... GOTM 17 has become an incredible crash nightmare, much earlier in the game than my previous crash issues and despite being on lowest graphics. It even crashed while the computer was idle

... I stepped away for something to drink, and came back to a reboted machine with the "recovered from a serous error" message that the "thread stuck in device driver" video crash always produces.
It has crashed five turns after a previous crash during a long play session, which combined with the crash while idle makes me wonder if overheating is an issue ... the HP notebook for gaming does get significantly warmer than my Toshiba used for productivity apps (lower end, more security). Toshiba is Intel Centrino Duo, HP is Turion 64. Of course, the game machine gets warmest when playing Civ!
I'd go bigger

Most likely neither laptop is what is traditionally called 'portable,' none of the laptops that are can possibly play Civ4...so why not go for the nicer, bigger screen...oh and the addition of a 10-key on 17" screens is a big plus...allows you to move your units in all directions without needing to click every single time...its the one thing I wish my 15.4" Dell had the most.
@ Thrallia: I don't compute in transit, so I don't need an airplane notebook. Just need to move it from site to site so a big notebook works. The 15.4" Asus has a 5400 RPM HD vs 4200 RPM on the 17" Toshiba, and Asus claims to have packed 512 Video ram on their card, vs, 256 on the Toshiba. The Toshiba's card (GeForceGo 7900 GS) is a class 1 card (top tier) scoring 3800 on their test and is said to have 20 pixel pipelines and 7 vertex pipelines on the following site:
http://www.notebookcheck.net/NVIDIA-GeForce-Go-7900-GS.2133.0.htm
The same site says that the Asus' card (GeForce Go 7700) is a class 2 card scoring 2700 on their test (presumably with 256 RAM as that is what the site says the card has) and is said to have 12 pixel piplines and 5 vertex pipelines.
Any idea if bumping the RAM to 512 on the 7700 takes its performance above the 7900GS? Or does number of pipelines rule? Is the HD RPM difference significant for Civ?
Either one has to be better than my current GeForceGo 7200, which the site says is a class 4 card (out of six classes), scoring 674 and having 4 pixel pipelines and 3 vertex piplines.
Everything else seems to work and just playing the latest GOTM with HOF update 11 started working yesterday. The movies startI dont watch all of them.
@ g_storrow: Nice to know. Thanks!
The hard drive on my old computer went out on me back in February. This was right after Vista for the individual was rolled out, so I picked up a new HP Pavilion system with Vista (Home Premium), 2 GB of memory, and an Nvidia GeForce 6150LE video card. First time I could see any of the videos, run the multi-character units and keep animated display on! Much nicer appearance.
Vista does do a few quirky things (I've had to do some hunting around to see where my save files go), but the games have played fine, both Civ3 and Civ4, including the HOF mods.
@ civ_steve: More encouraging news, thanks

Your system is a desktop sytem I assume, since the card is not a "Go"? The 6150 Go is even lower end than my 7200 Go, while the 6150 LE for desktops has 128 dedicated and up to 319 total after adding the TurboCache shared max (per Best Buy specs for their HP's with 6150 LE). My wimpy 7200 Go has at most 64 dedicated and perhaps as little as 32 (different sources say different things).
