How to upgrade
You're considering several options to boost performance on your Intel 6800k setup. The best path depends on your priorities—budget, upgrade feasibility, and desired speed. A used 6950X offers a solid balance of cost and performance, while a used Xeon CPU could provide more power if you need heavy workloads. Swapping components is a major investment but gives you the latest hardware. Evaluate your usage patterns first, then weigh each route carefully.
Unless you can find the 6950X at a very low price or your needs expand linearly with more cores, consider selling your components and purchasing a newer model. The 12th generation Intel processors offer much better single-thread performance compared to older Xeons. For example, the Xeon E5 2699A V4 is surpassed by the i7 12700, yet you can acquire the board and CPU for less than the price of a new Xeon on platforms like eBay (using current US prices). If virtualization is a priority and you require many threads, opt for the latest CPU generations. The Ryzen 9 series excels in virtualization tasks due to its high thread count, eliminating the need to manage multiple core types and still providing solid single-core performance. Generally, unless you're looking at extremely discounted prices, it's wise to upgrade to a current-generation processor if threads are essential.
It largely depends on your needs. For virtualization work, I’d likely hold off on new CPUs until later this year because P and E cores struggle with virtualization. Intel processors remain the fastest overall, though the 5950X is only slightly better than others in most scenarios—especially when you consider cost for similar performance. Unless there’s a compelling reason not to, I’d favor Alder Lake. However, some factors make it less ideal: high temperatures make SFF builds impractical with the 12900K, Windows 11 is needed for optimal results, and the new heterogeneous architecture suits only early adopters. Certain applications simply run better on AMD chips. Overall, you can't make a wrong choice, but I’d lean toward Alder Lake unless you have a strong alternative in mind.
