$5000 budget

I'm helping my friend build an iRacing setup. His budget is $5000. I put $2000 into buying him a pc (7800x3d, 4070 ti super, 32gb 6000mhz ram) and have $3000 to spent on the rest of the setup. I was wondering if any of you could recommend parts for an iRacing setup that would fit this budget. I was thinking of getting a 49 in ultrawide monitor but I’m open to suggestions.
