I agree with SaperPL, In my personal experience with both Sentry 1.1 and 2.0, I strongly suggest staying around 180W or less. Any more power/heat and no matter what gpu you have, green team or red team, it's going to completely saturate itself and the system with heat. Hot gpu's throttle (not necessarily because they hit their junction temperature but they don't boost as high as possible). So why get the 5700xt if it can't boost high enough to significantly beat the 5700 anyway? A 5700 will run cooler, quieter, and boost clocks better. You could put the extra money towards a larger ssd or something.
Ultra sff almost always requires some compromise. Ultimately its up to you though. There is definitely something bad ass about having a monster gpu in a tiny case.
Ej24 thank you so much for the watt recommendation. I didn't think about that and it totally makes sense. I'm just at 1440 with one 32 in monitor and it seems like the 5700 trades blows with the 2060S on most games, so if I wanted to go green or red, there seem to be options abounding. I've built lots of computers before, but this is my first foray into the SFFPC world and it has definitely been a learning experience. I can't thank you enough for the recommendation of wattage. I will try to stay around 180 ish watts.
