I'm finally upgrading after 10 years with my old 980ti and i7-6700k setup, and I'm looking to build the best gaming PC possible for a budget of £4500. I've already sorted out my motherboard for free and chosen a case I like. My goals are to keep core programs on a separate SSD and ensure decent cooling without focusing too much on RGB lighting. I'm open to recommendations about components, especially if that means downgrading the GPU to a 5080 for potential savings elsewhere. Now I just want to ensure that I get the most performance and best temperatures for my investment. Also, I already have a 4K 240Hz OLED monitor and all the peripherals, so the budget is solely for the PC itself.

Just a heads up, don't expect today's components to last another decade. The market isn't what it used to be. Focus on building something that can maximize longevity within the current standards.
I'd recommend skipping the 5090 and investing in a 9850X3D and 64GB of 6000CL30 RAM instead. You could even upgrade your SSD to a 4TB; this way, you'll be set for years!
I had a feeling the 5080 might be a better fit considering the price difference. Appreciate the advice!
Be mindful that the NV3 uses QLC flash which could affect its durability over time. It's best to put your Windows on the fastest drive for better performance—it's more demanding compared to games.
Your parts list looks solid, but you might want to get a beefier power supply for the 5090, like a 1200W version. Also, consider switching to cheaper RAM and SSD; they can perform similarly without the added cost. And if RGB isn't a must, opt for the non-RGB case version and grab separate RGB fans—they're usually a better deal!
Totally agree! Swapping the GPU for a 5080 could save you some cash too.

Thanks for keeping it real! I’ll aim for a build that lasts as long as possible.
