Welcome to the forums, newcomer!
Can you please parse links to both of the cards you've narrowed down? On a side note, it's best if you could parse your full system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
So we can identify any anomalies with your build and if your investment will be worthwhile. Also include your current GPU's make and model as well as the age of the PSU apart from it's make and model.
