4080 super and 4K 240hz monitor or 4090 and 1080p monitor 144hz?

Pretty much you can buy a 4080 super now and get a nice monitor or you own a 1080p and buy a 4090. Both come out to about the same price right now. 4090 $1700 4080 super $1000 + Monitor $6-700

Which would you do? Haven’t installed or opened my 4090 yet and I am kind of second guessing myself considering 50 series comes out in less than a year. Whereas I doubt there will be massive monitor progression by the time the 50 series comes out.

Also buy the 7800x3d or get a slower model and wait for the 9000 series?

Just looking for some thoughts!
