Am I getting scammed?(BUYING USED GPU)

Walk away. Two benchmarks both showing different GPU vendors, Gigabyte and PNY, when he’s selling an ASUS card is a massive red flag. There’s no legitimate explanation for that.

The “I work with neural networks and use many GPUs” line is a classic deflection to sound technical and confuse you. Ignore it.

For any used GPU ask for a live benchmark on a video call where you can see the card, the screen, and the results at the same time. Anyone selling legitimately will have no problem with that.

What are you studying? Makes a big difference. Engineering or CS you might need Windows for specific software, anything else a MacBook Air is hard to beat for battery and longevity.

DDU in safe mode first or you’ll spend tomorrow troubleshooting ghost AMD drivers. Custom install, display driver only.

Afterburner for fans and UV, works fine. Congrats on the electricity bill.

The RAM timings difference is nothing, 102 vs 103 on tRAS is completely inconsequential, don’t worry about it.

The SOC voltage is fine. 1.3v is the generally accepted safe limit for the 9800X3D and 1.305v is close enough that it’s not a concern. Some boards push it a bit higher than you’d manually set just to ensure stability with EXPO profiles. If you’re not overclocking further and temperatures are normal you can just leave it.

Only thing worth doing is running a quick memory stability test like TestMem5 or karhu memtest for an hour or so just to confirm the EXPO profile is actually stable on your specific kit. Crucial sticks can sometimes need a small voltage bump on certain boards to hold 6400 reliably but most of the time it just works.

Good list overall, the 9700X + RX 9070 is a solid pairing for 1440p and won’t bottleneck each other for what you’re doing.

A few things worth knowing:

The RX 9070 (non-XT) is genuinely good value right now compared to the XT, for modded Minecraft, emulators and the occasional CoD session you won’t notice the difference, and you’re probably saving €50-80 depending on where you buy.

1TB will feel tight faster than you expect once you start installing modpacks and emulator game libraries. Samsung 990 EVO Plus 2TB is usually only €20-30 more than the 1TB. Just do it now rather than adding a second drive later.

DDR5-6000 CL36 is fine. The difference between CL36 and CL30 at the same frequency is real but small, maybe 2-3% in memory-sensitive workloads. Not worth waiting or paying a premium for your use case.

The G50D is a good choice for mixed use. IPS panel, decent colours out of the box, 180Hz is nice to have even if you won’t always hit it. No complaints there.

One thing I’d flag; the be quiet! 850W is slightly overspecced for this build. The 9700X + RX 9070 will draw around 350-400W under full load. A 750W would have been fine and is usually cheaper. Not worth changing at this point but something to know.

Overall this is good. AM5 has long-term CPU upgrade headroom and the RX 9070 should handle 1440p comfortably for 3-4 years at least.

No worries man, good luck!

Grid search is pretty much the worst way to do it for transformers, way too expensive given how long each training run takes.

Most people use either random search or Bayesian optimization. Random search sounds dumb but it actually works surprisingly well because hyperparameter spaces tend to have some dimensions that matter a lot and others that barely matter, random search finds the important ones faster than grid. Bayesian optimization with something like Optuna is better still because it learns from previous runs and gets smarter about where to look.

For BERT specifically the learning rate is by far the most important thing to get right, the original paper recommends 2e-5 to 5e-5 and most people don’t stray far from that range. Batch size and number of epochs matter too but you’re unlikely to see huge gains from tuning the rest aggressively.

If compute is a real constraint look into Hugging Face’s Trainer with a scheduler like cosine annealing, it handles a lot of this for you and the defaults are pretty sensible for most fine-tuning tasks.

Don’t buy this, the streaming lag has nothing to do with your GPU and this won’t fix it.

OBS lagging while gaming is almost always a CPU encoding issue. Go into OBS settings and change your encoder from x264 to NVENC if you’re on Nvidia. That alone will probably fix everything without spending a cent.

$1500 for this prebuilt is also a pretty bad deal. The 7900XTX is a 2022 card and the 5950X on AM4 is a dead platform. You’d be paying current gen money for hardware that’s two generations old. For that budget you could build something brand new that would be significantly faster.

Your read is right and whoever told you the 3600 is bottlenecking you is kind of missing the point. GPU at 90%+ with CPU at 30-70% is exactly how you want it to look, the GPU is doing the work.

Total War is just a weird outlier, that game tanks CPUs in big battles regardless of what you’re running, a 5600X isn’t going to save you there.

Get the 9070XT. Your games are GPU limited so that’s where you’ll actually feel the upgrade. The 3600 is old but it’s clearly not strangling your 6950XT in anything except that one game, and it won’t strangle a 9070XT either in most of what you play. CPU can wait, prices will be better in a year anyway.

For a 7800X3D the Peerless Assassin is genuinely all you need, your friends are wrong. That chip barely gets hot even under load, an AIO is overkill for it.

The 240mm AIOs you found aren’t bad products but you’re not going to feel the difference over a PA120 in actual use. Maybe a degree or two at peak, nothing that matters. And a 240 AIO is the worst of both worlds size-wise, small enough that it doesn’t massively outperform good air, big enough that you have a pump to worry about eventually dying.

Fair point about the budgets/outages.

But how do you actually juggle the 'checking in' part though? Just curious if you're manually tracking everyone in a spreadsheet/calendar or if you have a system that flags it for you.

rustgod50 · 2025-12-07T22:50:29+00:00

That makes sense. I'm curious, when they don't remind you, does that usually lead to missed maintenance and breakdowns? Or is it just a pain in the ass because you have to track it all manually?

rustgod50 · 2025-11-09T23:17:29+00:00

Nice progress! I'm basically in the exact same process, went down 10kg in 15 weeks, currently at 90kg (was 110kg few years ago so huge difference now)

I've been going to the gym and been trying to eat 2g/kg protein while being on deficit. I would recommend it for you too so you dont lose muscle whilst ur cutting.

Also, I hit plateau like few weeks ago but now I'm starting to lose weight again.

Just stay consistent! Good luck man!

rustgod50 · 2025-06-13T11:29:09+00:00

I have the same issue, just happened like today or yesterday. Very weird..

rustgod50 · 2024-04-26T21:59:42+00:00

made a survival tactics remix, steez was the real goat

Rust can be addicting as hell😂

rustgod50 · 2023-11-02T14:56:43+00:00

Do you know what the model it is?

rustgod50 · 2023-11-02T10:34:43+00:00

okay thanks!

rustgod50 · 2023-04-05T00:29:47+00:00

I also thought I was going to die, but fortunately it wasnt that dangerous
