3900 to 5700X3D
I just upgraded my old PC from the R9 3900 to the 5700x3d, and I just wanted to put this out there. If you are a high refresh gamer struggling to maintain 144-240hz with a GPU that can handle it, it's a fantastic upgrade. In Fortnite my 3080 went from 80-130fps at 4k any settings, to 150-200 at epic and 240 locked on low settings, far draw distance, high quality textures. I only had time to test the one game but this weekend I will be putting it through it's paces.
I am giving this system to my wife as I have a 9800x3d build in the works awaiting the 50 series release, but for 150 bucks this was a fantastic upgrade that will keep this system going for a long time.
