You can run a similarly sized model - Llama 2 70B - at the 'Q4_K_M' quantisation level, with 44 GB of memory [1]. So you can just about fit it on 2x RTX 3090 (which you can buy, used, for around $1100 each)

Of course, you can buy quite a lot of hosted model API access or cloud GPU time for that money.
