Dual AMD Radeon AI Pro R9700 or dual NVIDIA or RTX 3090.

A user is building a dual GPU system, initially aiming for 30b at FP8 or 70b at Q4 with two AMD Radeon AI Pro R9700s. However, they found two new NVIDIA RTX 3090s for $1600 each, with a discount for buying both. RTX 40/50 series and RTX PRO 6000 are not options. The user currently uses a Studio M1 Max with 64GB RAM and an AM4 box with a 7900 XT, intending to reduce frontier subscriptions to one for coding.
