So, I recently bought an MSI RTX 2080 Ti Gaming X Trio, which is amazing, but I may have gone overkill, as my current CPU is only an i5 8600 @ 3.1GHz. I've been testing games like Red Dead Redemption 2 and been monitoring the temperatures closely. I've noticed that the temperatures for the CPU itself are around 70°C - 80°C, with its usage being at 100%. As for the GPU the temperatures, they're around 65°C - 70°C. Are these temperatures okay? I would upgrade my CPU to something like an i9 9900k, but I would then need to upgrade my motherboard (Z370-A Pro), which I really don't want to do. What's my best option?
