Hi there, I bought a prebuilt PC a couple years back and am currently trying to enjoy BO6 but my game starts stuttering significantly after 4-5 games. I was looking at upgrading my PC maybe and was wondering where to start? Currently have a GTX 1660 Super, i5-10400F, 16GB RAM. Not very knowledgeable in this area so looking for assistance. Reasonable price for a part time worker/student
