I'm planning on purchasing one of these cards and but I'm not sure which will preform better for my situation. I don't know much about how this technical stuff works but I do know that my 6gb of vram is not enough for 128x modded mc texture packs. I'm hoping you guys could help me figure out whether the higher performance 10gb from the 3080 will preform better than the slower 16gb from the 6800 thanks

I have a 512x Custom Night Sky texture pack with BSL and SEUS shaders that I'm experimenting with. The GPU is an EVGA GeForce GTX 1650 Super, and it runs one of the two shaders + the 512x Custom Night Sky texture pack + two resource pack overlays that I use. The RAM that I have is DDR4-2133 mHz. Everything is at max settings (Fancy graphics), and I still average around 140 in multiplayer worlds, (1.16.4), and ~200-300 in singleplayer worlds. Since your new GPU, whatever you choose to buy, will be a lot more powerful than mine, so you'll be just fine with your 128x modded texture packs.
However, as TileEntity stated above, you will definitely require a system with 16 GB ram or more. Make sure that you have at least 16 GB, and it be a higher speed, such as 2666 mHz, or even 3200 mHz. Both GPUs will handle the load comfortably.
I, however, will go for Team Green nine times out of ten, just because I can. That is, only if the two cards perform similarly. If Team Red pulls ahead by more than 10%.... I'll be cosplaying as Benedict Arnold very soon.
