I'm in the same boat as the OP except I have a evga 3080 xc3 (not tryna flex) and it's doing the exact same thing. I can boot into windows only with my cpu and my gpu unplugged for me to get past the bios. I have done all the requisite steps before hand. Really annoying, funny enough I wanted to test that it would boot regularly and had it plugged into the cpu and gpu lmao. Unrelated but funny
Edit: fyi I am on the latest bios beta update from asus, latest driver from nvidia and the latest vbios from evga
I can't say much since I've never owned an Air cooler, buuut you could always buy an Corsair H60 through Amazon Prime and if you don't like the results; return it at no costs
well you can save money by getting the oculus, with the money saved you could get a new CPU, MOBO, GPU, if you sell all the old parts as well. All your processing components just aren't powerful enough
1. you might (most likely will) run into a cpu bottleneck if you plan on running VR with games like Project Cars or other processing intensive games. 2. your GPU won't run well enough on lets say an Oculus, low frame rate is different when its right on your face. It will be discomforting and fatiguing with a 270. Take that information as you like
