Lenovo Legion 5 Pro (5800H, RTX 3070 140W, 16" WQXGA IPS 165hz 500nits 100% Srgb, 32GB, 1TB) $2,639.20 Delivered @ Lenovo eBay

Looks to be same model as https://www.ozbargain.com.au/node/643288 which I bought from. The 32GB RAM that mine came with was the decent faster timings, so no need to upgrade. I assume this model will be the same, but don't hold me to that.
Only difference being it is Windows 11. Ensure to go to https://www.amd.com/en/support/chipsets/socket-fp5-mobile/am… and update the drivers to ensure there are no performance issues with Windows 11.
Arguably the best 3070 laptop on the market right now.
