the new cpu arrive 31st jul from rumours, though not the 9800x3d..they haven't said when that will b4e, a few months later at a guess. thery've already said though at computex than the non x3d cpu's probably wont beat the 7800x3d for gaming, though will be close...guessing similar to the 7600x and the 5800x3d...downside is prices aren't release yet. they've said they wont increase prices compared to the 7000 series but you have to remember the 7600x was released at close to £300 and the 7800x3d was £450 at launch....so that's a lot of leeway in possible pricing
The motherboards wont be realeased till later in the year...they'll have usb4 on them, and aparently they'll be able to run higher ram speeds (I wouldn't be waiting for new mobo's personally), but that could also be down to the cpu's..up to you to wait for embargo on reviews and see what pricing will be...close enough that you could buy other parts though....that ram always runs out of stock for example and seems to take 6 weeks to come back into stock
edit: though you want the x3d cpu for flight sim, so you'll have to wait a bit longer for that
I'd be tempted to save £80 on the triple card 4070super, get something like below instead (though do like triple cards gpu's, but that's a big price jump for effectively the same performance). I'd say put the money towards a 2tb drive, but if it really just Flightsim you want to play, no point really
