Motherboard: b450-f CPU: ryzen 5 2600x Ram: hyperx fury 2x8 3200 GPU: Radeon Rx 570 4gb PSU: some 530W PSU I got when I was in need of a fast replacement Storage: 1 1tb gigabyte ssd Yes my ram is in dual channel and I manually set it's clock to 3200 and upped the voltage to 1.35V.

I recently got myself a ryzen 5 2600x with 16gb 3200 ram (2x8) in a b450-f motherboard paired with my previously owned Rx 570 GPU. Every game I play with I try to achieve 75fps matching my monitors refresh rate (1080p) and I mostly managed to do that. But with some titles mostly older like battlefield 4 or black ops 1 I experience stuttering without the fps dropping below 75. I also check frame timing which doesn't seem to increase or decrease during the stuttering. My CPU doesn't really reach above 60% usage and I try not get close to 100% usage on my GPU. I do run on my stock CPU cooler but it doesn't reach above 75 celsius during gaming sessions. My most recent title that I play with is call of duty modern warfare which seems to run fine to me even with another tab open on my second monitor stutter free only some occasional small drops in fps. Could it be some driver issues or something more serious? Thank you for your help in advance!

I havent overclocked it due to it being used.

Well after doing what you suggested it seems to be working fine. But just to mention the seller said he would take it back if any problem is detected. Should I just do that anyway?

I bought a used gtx 760 this monday the first minor issue happened yesterday, the taskbar had a slight discoloration like on the attached picture. After that today after quitting a game it went down to the lowest resolution while in desktop. A reboot fixed it. Then came this, also fixed by a reboot. Do I need to get a new GPU?
