It was pointed out in another thread that 2GB GDDR6X chips won't exist until next year. So as you said, the only way to go above 12GB before then is to adopt the 3090 form factor.All crying about 10GB you guys are wasting your time, 12GB is the 3080Ti max, so up to you if you want to wait for 2GB more, the Ti in my book is about more performance not more Vram. If the fabled 20GB 3080Ti comes out then expect to pay close to £1k+ as it is basically really close to a 3090 that sells £1.4k.
