H80i will struggle to keep 5900X's temp tame under elevated loads. I gone from R5 3600 to R9 5900X and I'm thinking now to keep the system past AM5, with 1 at least GPU upgrades in future. Most likely RDNA3 in the middle of 2023. I'm not confident an aging AIO designed pre-AM4 would keep a 5900x in the happy temp ranges for max boosting)

That CPU cooler may be a problem, most AIO's only last 2-3 years before they start losing performance or just outright die - the 5700x for example would easily be cooled on a basic 120mm tower cooler, while the 5900x needs a larger one or another AIOExtended Heatsink Design: MSI extended PWM and enhanced circuit design ensures even high-end processors to run in full speed. I don't see why you should be worried about worse performance. That should not be the case unless Windows is overflowing with gunk/half corrupt, or MSI somehow borked the specific BIOS revision you flashed. Do a clean install if you haven't in a while, make sure you get the latest chipset drivers, and be on a reasonably recent BIOS. Do a few simple benchmarks and if performance is roughly in the right place then there's nothing to worry about (e.g. 650/9500 CPU-Z, 1600/21k R23 etc) Core Boost: With premium layout and fully digital power design to support more cores and provide better performance.

is the better gaming choice with the single CCX design, the 5900x is better if you have multi threaded workloads or need the extra cache for something DDR4 Boost: Advanced technology to deliver pure data signals for the best gaming performance and stability so the issue is switched on pc and only got the mystic light, power led or hdd led don't light up and pc wont start psu is working and motherboard EZDebug led shows cpu as issue so was thinking cpu was dead. I know what a 2700X can do for gaming because my previous R5 3600 was around the same for gaming. Its not bad at all and could easily handle my RX5700XT which is about the same of the RX6600XT/RTX3060.So reseated cpu with fresh paste but still the same so gave in for the rest of the day but the next day switched on pc it worked for an hour but had to go out so shut it down and when i came home it wouldnt work again showing cpu as fault.

Unless you want to upgrade cooling too go for 5700X. Phillips 32 32M1N5800A (4k144), LG 32" (4K60) | Gigabyte G32QC (2k165) | Phillips 328m6fjrmb (2K144)
