Hi Guys,

I'm relatively new to PC building so please excuse if I make some errors regarding PC tech. I've decided to finally build my first High-End Gaming PC, this is what I was planning to buy:

Goal: 1440P, Ultra Settings, 144FPS Gaming on all Mainstream Titles (with upgradeability to 4K later)
Motherboard: MSI X670E Gaming Plus Wifi
CPU: Ryzen 7 7800X3D
GPU: Nvidia RTX 4080 Super
PSU: BeQuiet Pure 12 1000W

As you probably already know, Nvidia is going to announce their next 5000 Series of GPUs soon (End of September?).

My question is: Is it a good decision to build a completely new rig with an older graphics card (4080 Super) shortly before the release of the newer series? Of course its always better to get the latest parts, especially if they're about to come out soon. But with graphics cards, what I've experienced in the last few years brought up the fear that bots&scalpers buy up all the stock 5000 GPUs on release, the prices of the 4000 series will rise because nobody can get the newest gpu so they get the second newest, and in the end im stuck with buying an overpriced 4000 series or i have to wait multiple months or even years before I get to buy the 5000 series.

So my final questions are:

1. Is my current 4080 Super setup overkill for 1440P Ultra 144Fps gaming or not?

2. Do you think the prices of the 4000 Series will fall or rise with the release of the 5000 series?

3. Is it a good decision to wait for the relase of the 5000 Series before building my pc or should I not take the risk and build it with the parts available now?

4. How long until I can realistically expect to get my hands on the new 5080/5090 series ?

I hope I was able to formulate my questions clearly enough, thanks in advance for helping guys !
