I would suggest you be careful about focusing only on the price tag and instead look at the technical specs that actually utilize a 5090. You might want to consider the Dell Alienware AW3225QF 32-inch 4K QD-OLED because it balances the refresh rate with color depth better than most.

• Check for DSC implementation as it can sometimes cause slight artifacts or black screens when alt-tabbing.
• Make sure to verify the HDR peak brightness specs since many monitors claim HDR1000 but fail to sustain it.
• Consider the 240Hz cap; even a 5090 will struggle to hit that in every AAA title without some help from DLSS. Honestly, even with an unlimited budget, you should watch out for the coating on the panel. A glossy finish makes the 4K pop way more than a matte finish would, tho it does reflect more light. Just something to keep in mind so you dont waste money on a panel that might look dull in your specific room... it happens more than you'd think.
