Helpful thread, thanks guys. I read somewhere- can't find it now- something about different rendering engines having issues with NVIDIA vs Radeon GPUs. I can't remember what the issues were supposed to be- are they relevant to Blender and any of its renderers? Also, I'm pretty confused by the plethora of 3rd party manufacturers of RTX cards and their pricing. I see, for instance, a bunch of RTX 2080 cards priced around $680, and then one from Gigabyte priced at $89 bucks. Is it crap? Is it a mistake? Is there something missing?

Is this real?

Okay, wait... the site sells jewelry, not electronics... weird...
