I currently have a 990 pro 1tb that I can still return to Best Buy ($350). I am looking at buying 2 1tb wd black sn770’s for $150.

My question is would I miss the extra speed and power of the 990 pro or I would I not notice much and be just fine with 2 sn770 for half the price. I mainly only game and don’t really have video files or anything like that.
