Budget (including currency): $4500 NZD Country: New Zealand Games, programs or workloads that it will be used for: AAA title gaming, occiasional virtualisation, would love to play the new MS Flight Simulator well Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): I'm starting from scratch as I'm writing this from a PC built a decade ago and it seems to crash and reboot increasingly often. It's done this twice tonight and failed to boot one of these times. pbtech.co.nz / computerlounge.co.nz are my preferred retailers, particulrly the prior as its down the road from me. I cobbled together a rough list of items that I'd happily buy https://nz.pcpartpicker.com/list/dJm3TJ Component availability is really good in NZ for some reason, a couple local retailers seem to have 30+ of the EVGA GeForce RTX 3080 XC3 Ultra for example, so the world is my oyster, I'm sorry Basically my requirements are mainly 1. Have something that can pick up any title and max out the settings at 1440p ultrawide at 144hz, bonus points for 4k. 2. That case is preferred, but I'll take anything reasonably quiet, good airflow, USB-C on it 3. Quiet > RGB 4. Quite happy to spend on a 3080 The list https://nz.pcpartpicker.com/list/dJm3TJ I would love any recommendations, particularly for the cooler. I have an OG H100 from a long time ago that still works so I'm not put off by any concerns around AIOs but after watching a Linus video on AIO vs Air, I'd happy pick up a black Noctua kit, though PC Part Picker did hint at a compatibility issue. A side note is that I haven't purchased a new monitor yet either, so if anyone has recommendations for something that is 1440p ultra-wide that supports picture by picture (like the ROG STRIX XG43VQ, as I do play my console fairly often) that would be awesome. Thanks everyone!

In my experience, assuming Gig capable devices on each end it usually comes down to a cable. Rare, but it happens. Would be good to try with another device too, PC to second PC, second PC to modem etc.

Everything on your modem. Think of it as a pipe, ISP gets big pipe, you have a small pipe to your home. Someone floods that pipe, you get very wet and there's nothing you can do. This is generally why when you get DDoS'd restarting your modem is a legitimate tactic, your ISP will probably assign you a new IP as your old session is still active and the DDoS goes away. Unless you have a static in which case you need to wait it out, or get a new one.

What you're asking for is heading towards SME/Full Enterprise grade solutions. Next-Gen Firewalls such as FortiGate/Palo Altos can do this but it relies on a few things such as significant network segementation i.e. if one of your devices is compromised, there's no stopping it moving laterally if your whole network is in one trust zone or layer 2 domain.

You will want to use fiber here, you want to avoid ground loops caused by bridging two buildings eletrically with copper cabling. Conduit, run of fibre, cheap media converters or switches on each end with some SFPs from fs.com and you're done.

Yes, "up to" being the key word, your ISP is not faslely advertising here.

I wouldn't, their software is terrible for even advanced users. PfSense is not as bad, but it's also far from great IMO, I run this currently and I hate using it but I also can't be bothered replacing it unless it breaks. Would be interested to hear what OP's requirements are and if there's anything the UBNT suite is not meeting currently. Put the $1,000 into something else.

Aside from the other answers about VDSL inefficiencies, overhead and whatnot, you don't "pay for 75Mbps". You pay for a VDSL connection and it's best effort because there's simply no guarantees, particularly as it's over copper buried in the ground decadess ago.

In a lot of instances yeah you're running multiple fibers. In a larger setting where you're leasing fibres for $$$$/month, CWDM/DWDM and buying tuned transcievers is typically the way to go.

If it's raw internet and doing no inbound firewall policy, IPS etc then your requirements list is very small and a USG isn't a bad shout. The Sonicwall could be overkill. A FortiGate 50E could be a good alternative if you want the AV/IPS features.

Try set a limit it to say 1Mbps and see how it goes, otherwise maybe try a while without it entirely? Not sure what else you can do.

Not 100% of the time, individuals should test, this kind of advice can mislead people in entire countries into poor performance, e.g. every major free DNS provider is 30-35 ms away from me whereas my ISP is 3. That's not ohjectively true per my other reply. If you get better performance from another provider than your own ISP, sure, but for myself my ISP will serve me a response in 3ms whereas every major alternative is at least 35.

Where do you get the 100Mbps from? Seems to be its VDSL capability which is quite high end actually, that's the maximum throughput of a VDSL connection - do you even have VDSL or do you have FTTH/Fiber??

Yeah it sounds like you're double NAT'ing, which is complicating things. What are the modes listed that you can run the wifi router as? It needs to act as a bridge of some sort. It sounds like the wireless access point mode isn't quite doing everything you need it to. You basically need to remove one of these as it's currently configured from the network.

It's because 3Gbps is total of both TX/RX capability, so 1500Mbps in each direction. They could be helpful and say 3Gbps half-duplex but that wouldn't look nice on marketing material.
