Solved What is the difference between these mother boards?

Specs: Windows 8.1
I want to upgrade my hp dv5-1235dx laptop. Basically, I want it to be an all out laptop. All the features, bells, and whistles that could be squeezed in to it from the available options with Intel processors. I think it would be called an elite book of the time. I have been researching my options through the Maintenance and Service Manual through hp.com. A few things that I am confused with about the boards listed. What is the difference between PM45, GM45, and ICH9M? The manual has 4 boards listed for options. This board (With PM45 Northbridge and nVidia NB9P-GS discrete graphics subsystem memory and 512-GB of graphics subsystem memory) and this board (With PM45 Northbridge and nVidia NB9M-GE discrete graphics subsystem memory and 256-GB of graphics subsystem memory). I am pretty sure I am either one of these (With GM45 Northbridge and UMA graphics subsystem memory or With ICH9M Northbridge and UMA graphics subsystem memory) at the moment without tearing it apart to confirm with the part numbers. I have a little understanding of CPU and chipset compatibility but not much. Thanks for any information in advanced.

Your dv5 is 8-10 yrs old. No matter which Intel board you "upgrade" to, it will still only support Core Duo or Core 2 Duo processors, DDR2 memory, & weak graphics.

The boards listed in the maintenance guide have several errors in their descriptions. There are no graphics cards that use 256 or 512 GB memory; it should be MB. And there is no "ICH9M Northbridge". ICH means I/O Controller Hub which are Intel southbridge chips. The ICH9M is the mobile version of the ICH9 southbridge.

The NB9P-GS is the GeForce 9600M GS & the NB9M-GE is the Geforce 9200M GS. Both are weak by modern standards. Of the 2, the 9600M is better. Find their performance rankings at the following site:

My advice to you is to leave your laptop as-is. If you need more performance, buy a new one.

That is exactly what I was looking for. :) You are right, it isn't broke. I have never had any complaints with this laptop. Excellent device! I will however be looking into modern motherboards. I will start from there now and build a frankenbeast of a system.
