TL;DR: I bought a prebuilt system 1.5 years ago that was good but the GPU was sub par want to buy a 1080 Ti, PSU (in order to keep it safe after the upgrade) and a new monitor. Wondering if there would be any bottlenecks or other problems that I should know about.
So I bought a prebuilt around 1.5 years ago and seeing the differences in my PC and other PCs made me want more performance from the beginning. It was enough for me for the around 10 months because I never played anything other than esports games, unless it was Skyrim, but then I started playing AAA games and I started to see that at low-medium settings on most games I would barely if not at all hit 60 fps at 1080p. Originally I thought of building my own PC but then I realized how stupid it would be for me to buy a whole new PC only 1.5 years after I bought one. So I checked what was in the PC and found out that everything was fine and the only outdated thing was the GPU which was a geforce GTX 650. So I decided that what I wanted to do was just buy a new GPU, PSU (because the one in my prebuilt is terrible and isn't enough to be safe with the 1080 Ti) and a new 1440p 144hz monitor. I was just wondering whether the CPU would bottleneck the GPU (even though I doubt it because I've seen people with a 2600k and a 1080 Ti) or there would be any other problems that I should know about. I might get more storage or/and memory too but that is pretty unrelated to this so I don't think it matters.
