Lenovo E-530 Help with Upgrades please.

Hello Everyone and thank you for the help in it man
A friend of mine gave me his old Lenovo Edge e530
I've already upgraded the spinning hard drive to a small SSD as I don't need a lot of space for this since I connect you with the servers in my house for most of my data. also upgraded the Bios .

I want to do some upgrades to  CPU Ram Screen and Wfi Card .  

It's running H0ET96WW(2.56) From 6-12-2025

here are my Questions  what Core I7  should I get for this ? 
I don't want this thing to throttle I running  I am using a Core 5   53210M as the cpu 

also is I'm only running   6 GB of DDR3 1066  
I'd like to up the Ram  to 16 GB 
is 1600 the fastest Ram I should use or can Go to 1866 or 2133

also thought of replacing the screen with 1080P one is it possible ?

maybe the wifi card so I get Both Bands .. again is it possible ?


thanks if have other upgrades I should do please  let me know in this thread .

Photos posted below. sorry they are so large .
