So I'm pretty new with computers, and I'm searching for some components online to build my first pc. I was just browsing eBay today, and I came across an INSANE deal for an MSI geforce gtx 1080ti with 11 gigs of vram. And by insane, I'm talking 44 buckaroos refurbished. That just seems way too low a price for me, but the seller has a rep of actually delivering good products and the shipping is free, meaning that if it were fake, they wouldn't make me shell out any more money, so it leads me to believe that it's real. However, I can't be sure, and I'm on a pretty tight budget, so I think I just need to know if anyone thinks it might be a bad idea. Thanks!
