My PC 10 years old this month and I really need an upgrade, I have a newer GPU so only need the rest of the fucking owl.

The biggest issue of course is the RAM PRICE, Do I just take the plunge and spend €1800 on 128GB of 6000MT CL40 RAM? Or do I pay more/gb for 64GB of faster RAM?

I'm buying to last me another 10 years preferably. I'll probably go for the latest top of the line AMD CPU and the best mobo/psu I can get.

I don't really have a fixed budget but I'm trying not to spend the next 6+mo worth of money on an upgrade.

Any advice?

Edit:

I use it for work, I work in tech, I run a lot of memory heavy stuff, I use it for CAD, dev, gaming, etc. I'm constantly running at 90% ram utilisation on my 32gb ram. I'll copy what I said below:

I'm sitting at around 90% utilisation constantly on 32 and FF keeps crashing because I'm out of memory.

I work in the tech field, so it's sometimes docker, lots of CAD, games (often with said cad program and browser in the background)

Current specs: i7 7700k, 32GB DDR4, 2080TI
