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 October 2025 Updates

The big news this month is some significant price movement in components, most of it in the right direction! 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 under $300 and $400, respectively, the GeForce RTX 5070 12GB at under $550, the RTX 5070 Ti around $750, and the RTX 5080 16GB at $1000. This is a huge change from months past, as many GPUs were going for hundreds of dollars over MSRP, but now some GPUs can be grabbed at under MSRP depending on the daily pricing. We’re also seeing incredible prices on the fastest Gen 5 SSDs, which once carried a huge price premium, but now we almost always recommend them over high-end Gen 4 SSDs. So for those on the bleeding edge, you no longer have to pay quite as much to have the best!

Now for the bad news: RAM is going up in price very rapidly. The mainstream tech media has not picked up on this yet, but they will soon enough. We’d go as far as to call this a crisis in the RAM market. In fact, we tracked it up about 15-20% in August and September, and shockingly another 40% in the first half of October, leaving prices at double what they were this summer, and they will likely keep going up. Whether it’s high demand, reduced production, tariffs, or something else, there is no denying that DDR5 module prices are now at their highest level since the early days of DDR5 technology. Luckily, RAM is still one of the less expensive components in most builds, but it’s suddenly a much bigger portion of the budget on cheaper builds.

So there you have it – the great, the good, and the pretty bad!
