L502x Processor Upgrade

I have been working on upgrade my laptop to work with solidworks better and needed a bit of help.

Here are the laptop specs running windows 10

2nd generation Intel® Core™ i5-2410M processor 2.30 GHz

16GB Shared Dual Channel DDR3 Memory (upgraded this)

NVIDIA® GeForce® GT 525m 1GB graphics

Upgraded to a SSD

What I would like to do is upgrade the two last things which are the graphics card (if even possible) buy getting a new board and the processor. 

From what I have researched these processors will work in the same socket as my i5 but which one is better and will there be a big improvement over the i5 that i have??

i7-2860QM
i7-2820QM
i7-2760QM
i7-2720QM
i7-2630QM

Lastly is it possible to upgrade the graphics card to the GT540m 2gb by installing a new motherboard? Will I gain much over the GT525??

thanks!
