I think RTX 5080 might end up being slower than 4090 by 10-15% in pure rasterization... Also People trying to sell RTX 4090 for 1 lakh or above might have a difficult time selling one, Unless someone needs that extra vram for some specific use case...
lmk which battery you bought, I need to get one for BVX1200li-in. This model has been a bad experience for me. Had bought two, battery died on both after like a week of warranty period
