My gaming laptop recently died, but replacing it immediately isn't essential because I can manage with an integrated-graphics laptop for now. I'm considering a desktop with a Ryzen 7 7800X3D, Thermalright Peerless Assassin 120 SE ARGB, Radeon RX 9070 XT, Lian Li Vector V100R case, and a 700W power supply. I would reuse my current 512GB SSD and either buy 2x16GB of DDR5 memory used for $300 or less or start with one 16GB stick and add another later if prices improve. I expect to need a more powerful dedicated computer next fall, but I could potentially wait until late 2027 or early 2028 for newer AMD and NVIDIA graphics cards. Would it make more sense to build now, or wait and upgrade when I genuinely need the performance?

If you can comfortably get by without a desktop, waiting is reasonable. A year probably won’t guarantee a huge price drop—maybe you save around $100–$200, but prices could also rise. Since you expect to need the system next fall, start watching for deals now rather than buying purely on speculation.
Do not use that Thermaltake Smart 700W unit with this build. It’s considered a very low-quality power supply and isn’t worth risking expensive components over. Choose a reputable 750W–850W model with a strong safety record and an appropriate modern efficiency rating instead.
Thanks for catching that. I’ll replace the power supply with a better budget-friendly model rather than trying to save money there.
Because the 7800X3D uses the AM5 platform, you need DDR5 memory. One 16GB stick will run in single-channel mode and can hurt performance, so 2x16GB is the better choice. If buying 32GB is too expensive, it’s better to wait or look for a reasonably priced matched kit than to plan around a single stick.
I’d rather stay on AM5 and pay more for DDR5 now than switch platforms and end up needing another CPU, motherboard, and memory upgrade sooner.
My bigger concern is having enough GPU performance when I actually need the computer, not just saving money. I’m wondering whether a 9070 XT would retain enough resale value to sell later and upgrade to a newer high-end card.
