Have you tried contacting the manufacturer of the video card you want? Sometimes they have wait lists you can opt into.

Yea, I'm on the waitlist for all the good it does me.

It looks like the higher end graphics cards are available new for no less than ~3x their MSRP. Everything else is sold out. In all seriousness, the cheapest option is to buy a pre-built computer and throw out everything but the GPU. It's insanity, and I can't wait for this fad to be over.

They are soooo receptive when you tell them you are just buying one.
