Welcome to the forums, newcomer!
You might want to stick to having one GPU maker in your build, to avoid driver conflicts, not to mention the need for a higher wattage PSU if yours has been around as long as the GTX970. What's preventing you from hooking up to multiple monitors while on the GTX970?
I can attempt to answers any questions that people may have.
How about you add this bit of info;
CPU: Ryzen 5 7600X
CPU cooler: Thermalright 120 SE
Motherboard: B650M-A AX II Prime
Ram: 1x16 G.Skill
SSD/HDD: (HDD) WD Black 320GB (If I recall the size correctly)
GPU: GTX 970
PSU: MSI MAG A650BN
Chassis: (I'd assume the case) Corsair 3000D
OS: Windows 10
Monitors: ASUS VA24E (60Hz) and a Polaroid TV (unsure of the model)
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
