Just keep an eye on Amazon GPU deal page, you will find best deals during Amazon Prime day: https://amzn.to/3RiURDV

It's hard to say for sure this far in advance, but based on past Prime Day sales, there's a good chance Amazon will have some solid discounts on NVIDIA graphics cards. Keep an eye out in particular for deals on the xx70 and xx80 series cards, as those tend to see the biggest price drops. I'd suggest checking deal sites and setting up price alerts a few weeks before Prime Day 2024 to get a sense of the best prices. But don't expect huge 50% off type deals - 10-25% off is more typical for GPUs.

I think RTX 3000 series GPUs will have a big price drop, while RTX 4000 series GPUs may don't have any huge rebates.
