Which GPU to get now that 5090 Benchmarks are live?

Edit: totally forgot to say the budget is around $500-$600 for a card.

I'm helping a friend build a new PC. He's coming from a PS5. We're waiting for the 50 series launch to decide on a GPU.

Right now he's purchased:

  • AMD Ryzen 7 9700X + Gigabyte B650 Gaming X AX v2 + Corsair - VENGEANCE RGB 32GB DDR5-6000. Micro Center combo for $440
  • EVGA 850w
  • Fractal North Case

Undecided:

  • Undecided on AIO
  • He is undecided on the Monitor, but he wants 1440p 144hz+

Given this, I'm leaning toward trying to help him find a used 4070 Super but wanted to get your thoughts. He also wants to use his PS VR with his PC to play Assetto Corsa VR.

He's big into story-driven AAA games, and he's interested in Ray-Tracing.

Am I missing something here, or is the 4070 super the play?
