In January I replaced my 5 year old GTX 1080 Ti with an Asus ROG TUF OC 4090. My old 1080 Ti never had an official waterblock made for it by anyone, so I was never able to incorporate it into my loop. I made sure that whatever model of 4090 I got, it had to have waterblock support from more than just one vendor. I'm finally done with my system. For now anyways. After years of tweaking, upgrades, and loop rebuilds, I'm happy with how it looks, and how it performs.

There's a good chance however that next year when the Ryzen 8000 chips come out I'll upgrade my platform to that. But for now I can finally enjoy the months of hard work and waiting for parts.
