I'm doing a major upgrade for my brothers computer.
He has a gigabyte GA-Z77X-D3H motherboard with windows 10
- 2nd gen i5 processor 3.3HZ,
- 8GB of DDR3 1333,
- a R7 250 graphic card with 1GB of memory,
- and a 1GB Seagate SSD

The improvements are
-I'm upgraded the CPU to a 3rd Gen i7.
-Upgrading the graphic card to a RX550 4GB memory
So now comes the memory for the same price I could
1- max out the memory to 32GB of DDR 1333
or
2- 16GB of DDR3 2133

which do you think would yeild better results?
