The TBG DIY PC Build Guides
Introduction to the TBG PC Build Guides
Welcome to TBG’s DIY PC Build Guides! This is where you’ll find all the best PC builds on the ‘net, from ultra-compact home office PCs to screaming-fast gaming towers. In total, we offer 15 distinct DIY PC Build guides, constantly updated with the latest and greatest components.
The September 2025 Updates
Things are looking great in the DIY PC market for the first time in a long time! CPUs and GPUs are generally available at or near their MSRPs, the prices have come down on high-end SSDs, and there are many great new cases to choose from that offer a wide range of styles to suit any preference.
The big news this month is that we’ve increased the budget target for two of our most venerable builds, which have both been on this site since our founding in 2013. Over the years, thousands of readers have built our $500 Home Office PC and our $750 Budget Gaming PC, but we made the difficult decision to add $100 to their price targets to give our readers much, much better builds for just $100 more. These now become the $600 Home Office PC and the $850 Budget Gaming PC. We figure that given inflation and other factors, our readers will understand. We just weren’t comfortable with what we could list at the original price tags – in fact, we considered taking these guides down entirely, so hopefully you all feel this was a decent compromise! By the way, one deciding factor here was the termination of DDR4 memory production globally – now every single one of our builds uses modern DDR5 memory!
Let’s move on to the component update. For CPUs, AMD has the market essentially locked up, and for the first time ever, AMD’s market share surged to over 30% in mid-2025, and is climbing rapidly. If you’ve read about Intel’s travails (and who hasn’t), this is a clear indication of that. In terms of GPUs, both Nvidia and AMD have good deals available, at different price points. Among our favorites are the Radeon RX 9060 XT 8GB and 16GB at around $300 and $400, respectively, the GeForce RTX 5070 12GB at under $600, the RX 9070 XT 16GB at under $750, and the RTX 5080 16GB close to $1000. At the very high end, the RTX 5090 is now fully available, and while it’s hard to score one at the $2000 MSRP, the premium isn’t outlandish for a GPU of this caliber.
So there you have it – the latest, the greatest, and the nitty gritty!
