Sanity check request! Part list is basically finalized, requesting a final check for incompatibilities or other issues between parts that I'll keep from my current PC and new parts!

PCPartPicker Part List

Ignore prices: I'm going to buy from different stores and I couldn't bother inputing prices manually actually went and edited prices, also removed unnecessary bits as they were causing some confusion haha

This part list fits my budget and it's unlikely I will make changes to it, unless there are big issues with compatibility in which case the only change I can make is to go for a 7800XT instead to open up some of the budget to fix those issues.

Objective is playing AAA games at 3440*1440 100+ fps (ideally 120+), high-ultra with no RT and hopefully no FSR; what I'm keeping from current build are RAM and MoBo (plus case, CPU cooler, fans, and drives, but these shouldn't cause any issues). I listed current drives, fans, etc. just to get a somewhat accurate total power draw to pick the right PSU.

I know about case GPU length restrictions, that's why there's a slim fan in the list that will be mounted front bottom, to accomodate the long GPU (Fractal's website says maximum GPU length with front fan is 315mm, standard fan is 25mm deep, 7900XT is 320mm and the slim fan is 16mm deep, so I should have 4mm of wiggle room!).

My main doubt is about huge bottlenecks with either RAM or MoBo. I'm keeping those and I'd rather not change them, because that would mean having to get a 7800XT instead (I know, for example, that a faster and lower CL RAM will give me slightly better FPS, although my current sticks are running at 3466Mhz and CL18, so not too bad, but I'm not looking to min-max to the last minute detail), unless such dated parts would cause huge bottlenecks that would make that GPU a total waste.

PC will be used exclusively for gaming.

Thanks for any and all suggestions!

edit: after a bit more researching, I ditched the AOC U34G3XM and picked this Gigabyte after watching the video by Hardware Unboxed

The only bottleneck I see is the PCIe on the motherboard, which is only 3.0 x16, while the 7900XT is 4.0 16x. Not the end of the world, though, so I will pull the trigger in the next few days. Thanks everyone for your help!

What's the reasoning behind the the 3TB in hard drives?

Data hoarding haha I know it's not ideal, and I will build a NAS at some point, but at the moment high-res, high-fps, high-details gaming is a priority!

Fwiw, I would absolutely not use a 1TB spinny drive. Just find a 4, 6, or 8TB drive. Prices tend to bounce around some, but It’ll be only slightly more expensive (I’m looking at a 6TB 7200rpm drive for $80 on Newegg right now) than that 1TB drive you found.
