I bought an Alienware Aurora R4 back in January of 2013 and figured it was time to upgrade the GPU.

Currently, the GPU=4GB GDDR5 Nvidia GeForce GTX 690, RAM=32GB Quad Channel DDR3 at 1600MHz, CPU=Intel Core i7-3930K (6 Core, 12MB Cache). The PSU=stock, Motherboard=stock. I'd like to upgrade the GPU to a current Nvidia GeForce RTX 3080, but don't know if it's compatible. Nvidia only shows 4 options in the 30xx series on their website. Can someone confirm if the 3080 would work or not? Any experience with a successful 3080 upgrade on an Aurora R4? If not, what's the next best option?! Any necessary BIOS upgrades, etc?

Thanks for any advice or general comments in advance. it's appreciated.
