1GB would be gruesome slow on Vista.
I've got an old Dell D620 Latitude Laptop
Specs:
Processor: Intel(R) Core(TM)2 CPU T5500 @ 1.66GHz
Memory: 1.00 GB
OS: Windows Vista Business, 32-bit Operating System
I was looking at upgrading my memory from 1GB to 4GB and possibly upgrading my SSD.
This is my last bit of hardware that is still working, so I'm trying to stretch this one out as long as possible. I would like to be able to browse the internet smoothly, and if possible but not needed play League of Legends (System Requirements: http://www.systemrequirementslab.com/cyri?gameName=league-of-legends&itemId=10933&p=r)
All while trying to ball out on a budget, any and all advice would be greatly appreciated.
Sincerely,
Snorlax
