Totally not worth it for $400. Prices of video cards are dropping each week, a single 3070 is a much better solution, as long as it fits.
I have an Alienware Aurora R8 and I'm thinking of upgrading my graphics card. I have the dell branded RTX 2070 that came with my machine still in it. I was initially going to buy a RTX 3070, but then I started wondering if I could just buy a second 2070? I can get another of the same exact card on eBay for about $400 which is a bit cheaper than the 3070. I thought maybe dual 2070s would probably be better than a single 3070. So my main questions are, is it worth it? Will it fit? Will it even work?
Aurora R8, dual RTX 2070?
