So I've recently built a whole new machine, and just finally got the GPU, a 2080ti. I put it in and was surprised at the poor performance. I'm getting 40-60ish frames at 1080p where most benchmarks for the same card and the same games are getting higher frames than that at 4k. I've set the PC to max performance, I have the latest NVIDIA drivers, my power supply has plenty of wattage I've got two separate PCIe cables, etc. Something is wrong, and my intermediate PC knowledge has failed me. Help please?
specs:
evga rtx 2080 ti xc ultra
ryzen 5 2600
corsair vengeance lpx 16gb
msi b450 tomahawk atx am4
evga supernova g3 650w
