Hard to help you when we don't get the details we request from you.
BTW, in my searching I found LG makes an UltraGear OLED 45" curved monitor. It's not the super wide 32:9 the G9 is, but at 21:9, it's still wide enough to give good peripheral view in race games and 21:9 is also FAR more supported by devs in general.
The res of the LG is 3440x1440, and it's refresh is 240Hz, which would mean you could run F1 22 on a RTX 4080 and average roughly 240 FPS. At it's current $1500 price, the 45" LG UltraGear is right in between what the two higher end G9s cost.
I've seen/read reviews on both these curved UltraGear and G9 displays. The nit pick about the G9 is typically the motion blur and need for very powerful GPU. The nitpick about the UltraGear is it's not quite as good for net surfing, as the text isn't quite as sharp. Some have bought the G9 and returned it and bought an OLED and say it's much better for gaming with zero motion blur and near zero input lag.
Note as well that LCD display manufacturers always state best case scenarios for response times. If an LCD manufacturer is claiming 1ms response time on an LCD, that is the very quickest it can do from one color to another. The average response time can be MUCH higher, peaking as high as 16ms.
OLEDs don't have afterglow like LCDs because their pixels are transistors that are self lit and instantaneous, whereas LCD crystals need to align with different voltages for each color, and be lit by LEDs. Therefore LCD screens will never be anywhere NEAR as close in response time as OLED, despite the 1ms claims. It's literally like comparing a micro chip (OLED), to a PCB with components soldered to it (LCD).
Lastly, while I know it may seem like I'm pushing Ultrawide vs Super Ultrawide, and OLED, when you're spending well over $3000 total on PC and display, you may end up taking on other type games, either to justify the expense of it, or just because the experience is so immersive. In that scenario, 32:9 is easily dwarfed by 21:9 as far as how many games support it, and in many games that have a fair bit of verticality to the maps, the limited height of a 32:9 is going to feel cramped.
As far as display type goes, LCD is getting quite antiquated, and OLED clearly has the sharpest picture quality and fastest response time, both of which are very noticeable in fast action games like racing.
