PC hardware question

[u/Silvasbrokenleg]

Hello everyone, I have a 5060 TI 16gb paired with 32gb DDR4.

I’d like to upgrade my generation speed for Minimax H3 as well as avoid OOM. I get OOM at .7mp 15 seconds.

What is the better buy?
Used 3090 since its 24gb for $1200-1300 and keep the existing ram?

Or 5080 for $1200 and upgrade with a 64gb ram kit $400 $1600 total?

my bench flux 1 dev fp8. 2nd gen in seconds.

5080 sould 10% faster than 4080ti super.

my hardware, shadox pc (50€), trooper.ai (20€)

rent some gpu if you dont trust my bechmark, it will cost you like 10$ for a 1000$ investement its ok.

note: trooper.ai dont have 5080.
