LG 34GP83A vs Alienware AW3420DW

I know there are a lot of posts about this but I was looking for insight based on my desktop. I really can't decide which one to buy and there's no where nearby I could ever see these monitors in person.

Processor: Intel(R) Core(TM) i7-8700K

RAM: 16 GB DDR4 @ 3200 MHz

GPU: ZOTAC GeForce GTX 1060 6GB

I do plan on upgrading my GPU to a 3000 series once I'm able to purchase one at a reasonable price but obviously that could take a while given the market situation. I'm thinking more of what's best in the long run since I will be upgrading the GPU. Is the Alienware worth the extra money because of the G SYNC module? It seems in many aspects the LG performed better on the rtings.com review against the Alienware but once I have a 3000 series card will the G SYNC module be that important? I will be working from home multitasking a lot but I will be gaming in my spare time and watching movies etc.

As of now the LG is 799.99 USD new and the cheapest I can find the Alienware new is 995.99 USD.

Through amazon warehouse I have found the LG for about 760.00 USD (I would just buy the new) and the Alienware for about 850 USD.
