The $1200 Upgrade Dilemma: Is it Worth It?

You’ve allocated approximately $1200 for potential upgrades and are contemplating whether it’s worthwhile. Considering your existing hardware:

  • RTX 4080 / 13700K: This is a top-tier gaming configuration that will remain relevant for years to come.
  • RX 6900 XT / 10850K: Also a very powerful system, capable of excellent performance.

Your assessment that the 9070 XT is only marginally better than your 6900 XT and that a 7900 XTX offers similar performance to your 4080 is accurate. This suggests that the most significant performance leaps would come from components that are at least a generation or two ahead, or from a complete system overhaul.

Where $1200 Could Be Best Spent (If You Decide to Upgrade):

  1. CPU Upgrade for the RX 6900 XT System: While the 10850K is strong, a newer CPU could offer substantial improvements, especially if you were to pair it with a significantly upgraded GPU later. However, without upgrading the GPU, the gains might be incremental for gaming alone.
  2. GPU Upgrade for the RX 6900 XT System: If you were to upgrade the RX 6900 XT, you’d be looking at something like a RTX 4080 Super, RTX 4090, RX 7900 XTX (which you already consider similar to your 4080), or the upcoming RX 8000 series. A significant GPU upgrade for this system would likely consume most of your budget and might push you beyond the $1200 mark for a truly substantial leap.
  3. New System Focus: The most impactful use of $1200 might be to consider it as a down payment on a new, dedicated Linux workstation or a future upgrade path. For instance, you could potentially build a brand new, moderately-specced Linux gaming PC, or use it to upgrade key components on one of your existing systems to better align with your Linux goals.

Our Opinion: Given that your current systems are already incredibly powerful and that you are contemplating waiting for a “50% upgrade” over your 6900 XT, it might be prudent to hold off on the $1200 upgrade for now. Focus on optimizing your existing hardware with Linux. The performance gains from a clean Linux install, particularly with the KDE Plasma desktop and optimized drivers, can often feel like a significant upgrade in itself. You can then re-evaluate your hardware needs once you’ve fully experienced Linux gaming and have a clearer picture of what you might be missing.
