VRAM Amount? And or upgrades for BeamNG.Drive?

Ok so. 3080 ti and 3090. 3090 is slightly more but 2x vram but they both have useually the same performance. How much does VRAM affect it. Im getting a 10 gb 3080 or possibly 12gb modle which is 10 fps less on avrage than 3080 ti / 3090 im just worried if the vram useage will bottleneck my performance and i should just get 12gb version or just cough up more for the 3090. Or just wait for RX 7000 and RTX 4000 which will have more power but for smth like 4070 will have same Vram as 3080 12gb and 3080 ti for me personally i do not need anything that much more powerful since i mostly only play beamNG, stormworks, Snowrunner, and plan to do blender in the future. Im too rushed to wait so im probably not going for ryzen 7000 and RTX 4000 series especially if i want to keep my 850watt PSU anytime soon. Still will probably have to upgrade if i want a 3090 tho -_-


Ps this will go to a new PC. The new pc will have


Corsair 850watt 80 plus changeable if i get a 3090 or ryzen 7000 or rtx 4000.

Ryzen 9 5900x 12 core 24 threads more than enough for beam traffic 10 cars.

32gb 3600mhz ddr4 RAM corsair

2tb ssd Samsung No SATA / HDD if you think thia could cause a prob in nee pc for beam mostly tell me.

RTX FTW3 3080 EVGA can or will change to a 3090 or RX 7000 or RTX 4000 if prices drop or need the boost. (Maby ill even upgrade to a "GTX" 970 )

And ofc ill get 10 FANS BECAUSE COOOOLLLINNNGGGG. Any tips for a better BeamNG experince and or upgrades at almost no cost this pc will be 2.1 - 2.5k with the 3080 i get 2.1 k so i got space to upgrade


Thanks for reading any help, helps!
