One of my buddies is overclocking his CPU to hit 8 GHz, and the results are laughable. His RAM keeps corrupting and his fluid cooling system is almost at its breaking point

Signal integrity of your parts start breaking down at higher and higher clock speeds, doesn't matter how much liquid nitrogen you use.

Not sure off of the top of my head, his rig is retarded though, easily 5k+

I had an adventure. Since ddr5 has come down in the year since I built my pc, I picked up another 2x16 kit of the same exact model, figured I'd fill all 4 slots. Popped it in, saw task manager showed 64gb, Bob's your mother's brother.
Then after plugging everything else back in, refused to boot. I try everything, no luck. Pull the 2 news sticks - it boots. Cut to many hours later, I figure out the pattern - 4 sticks works on first boot, but no matter what speed or timings I choose, the next boot always fails until the sticks are removed.
I contact Gigabyte support, they get back to me within 24 hours saying '4 sticks will only work if you decrease memory speed, also that ram's not on the QMV, go suck a dick.' Nevermind I proved it does work on first boot, and it's EXPO ram in an AMD system.
Another few hours playing around I fix it. There's an option called 'Memory Context Restore' which seems to store the training results after boot, so the ram is only re-trained if there's a config change. Without it enabled, it does a full retrain on every post, meaning booting taking over a minute, but it works everytime (and at the EXPO speed of 6000 cl36).

Well I got my motherboard in. At the end of the week I'm picking up my graphics card. Probably a cheaper 4070 super than I first picked but still a 4070 super, or possibly just a 4070, depends how I'm feeling.
Also a ATX board is fucking big.

What is probably going on is that, at that clock speed, you have cross-talk/signal integrity problems in the DDR channel itself. Thus it's sensitive to small variations in operating conditions, but you're juuuust inside an envelope where it will still work if you recalibrate the system every time.
I have a server node with right now a few terabytes of RAM, and if we use anything faster than DDR5-4800, the thing just will not run. Those DIMMS are packed in pretty tight.

Anyone have experience with a 7900xtx? I've been eyeing it for a while, curious on what other people's thoughts are on the card.

All I've heard is early on some had cooling issues. Other than that coil whine (which seems to be more of an issue across the board now, just banish the pc case to the floor imo) and the closer to $800 you can get one, the better.
Are you doing AI? If not, inb4 someone comes in with "but muh AI".

Seems fine to me, but I don't have high performance demands, gaming seems fine. Audio issues on Linux. AI works ok once you get it working... in Linux, no idea on Windows, obviously slower than a 4090 but it's nice to be able to play with LLMs(well, maybe not large, medium-ish)
but muh AI.

I have the almost 7900XTX, i.e. the XT. It's a good card, plenty powerful enough for any normal person imo. So you'll be a step up again. And despite the "muh AI" depending on what you're doing it might still be fine. I have mine doing quite well with ROCm under Ubuntu now. Though if you're serious about AI you still need Nvidia. I'm not a heavy gamer but I'll answer any questions I can. Zero problems with drivers or anything like that if that's what you want to know.

Yeah it's going for $300 over MSRP at the local computer shop. If I can find a better deal elsewhere that'd be great, but I'm probably gonna grin and bear it. Got a large tax return in process, so once that goes through it'll cover the costs for the entire build comfortably anyhow.
Nah, no interest in AI at the moment. Just feel like all that VRAM will pay off down the line for gaming compared to the 4080's 16GB.
That was the main worry I had. I've heard AMD drivers have started to come around recently, so I'll take your word for it.

This is testament to how long a fuck-up can follow you around. AMD drivers have been fine for a long time, ime. But people keep repeating this.

Best value: Intel
Best performance: Nvidia
There really is no good reason to buy an AMD card right now. For budget cards, the Arcs are the best. But through the entire rest of the price range, a 30 or 40 series Nvidia card is better than any AMD card in the price bracket.
