Helping A Friend With Computer Crash's Mac Pro...

He is running a Mac Pro.I think this is the computer he is running currently https://support.apple.com/kb/SP623?locale=en_US
Version 10.12.6
iMac (21.5-inch, Mid 2011)
Processor 2.5 GHz Intel Core i5
Memory 4 GB 1333 MHz DDR3
Startup Disk Untitled
Graphics AMD Radeon HD 6750M 512 MB

He is trying to run the game Rust.I told him you would not be able to get more then two hours of game play in.Due to the fact he is running only 4Gb of ram and a Graphics AMD Radeon HD 6750M 512 MB.

Is there any way to replace both the ram and video card...

Rust currently takes over 9gigs of ram on my system.With 10 gigs to spare.
