Nvidia announced their new graphic cards today. Top of the line RTX 5090 has a MSRP of $1,999.
The current 4090 goes for about that price right now, if you can find any. A 3090 can go for $1,500. That new 5090 might hit the shelves close to $3K.
Guessing that is the main reason Nvidia lost over 6% today. Although, I think most of those higher end GPU's are meant more for AI people than video game players.
