#1twiztidfreak6t9Posted 9/4/2013 8:44:52 AM
My specs are in my sig, and I see that this http://www.cpu-world.com/CPUs/Core_i7/Intel-Core%20i7-3940XM%20Mobile%20Extreme%20Edition.html as I'm seeing on the CPU-Z app is compatible with the motherboard "Socket 988B rPGA"......Am I able to upgrade the CPU to this?Also am I able to buy BD-Rom drive & replace the DVD-RW with it too?

If your BIOS supports it and the existing package does not use a ball grid array (i.e. it's not soldered to the motherboard), then it should be a simple matter of removing the old CPU and installing the new one... however, the i5-3210M has a 35W TDP while the i7-3940XM is 55W, so the cooling equipment of the laptop may not be able to cool the i7-3940XM adequately.
The i7-3940XM is a terrible value anyway...

Typically no. The highest end Sagers and Alienwares sometimes have this as a possibility but even in them its rare. Its much more common to upgrade a laptop gpu.

I wouldnt bother. Especially with an m14x. The price wont be worth it even in the unlikely event you can.

Er, not true at all. It's the other way around. Outside of Ultrabooks, it's common for a laptop to have the CPU be replaceable but not the GPU, except for in customizable gaming laptops. Most of your cheap, everyday laptop will have a removable bottom panel that will expose the RAM slots and CPU socket.

As for the TC's case, upgrading to a quad core CPU might be worthwhile only if you plan on doing anything CPU intensive. Games are probably going to be limited by that GPU in all cases. An Extreme series CPU is a big waste of money though.

I guess I learn something new everyday. I always thought it was much easier to upgrade a laptop GPU than the CPU.
