I've never built a PC before, but I'm planning a system for editing YouTube videos in DaVinci Resolve. I've been comparing GPUs such as the RTX 4060 Ti, RTX 5060 Ti, and Radeon RX 7700 XT, and used prices are often much lower than buying new. My main concern is that I don't have another computer available to test second-hand parts. If something fails after I assemble the system, dealing with returns, warranties, or troubleshooting could be difficult. Would buying used parts be reasonable, or should I buy everything new or choose a prebuilt instead?

Used CPUs and GPUs can be good deals, but you should verify that they work before buying. Ask the seller to demonstrate the part running, ideally with a timestamped video or an in-person test. For a graphics card, a GPU-Z screenshot and a short FurMark or similar stress test can help confirm that it’s genuine, stable, and not overheating. If the used price is only around 10–15% lower than new, the warranty and easier returns usually make new the better choice.
For a first build, I’d lean toward buying most components new. Having a warranty makes troubleshooting much less stressful when you don’t have spare hardware for testing. A used GPU is probably the one exception because it can save a substantial amount of money, while used RAM is also generally low-risk if it has been tested. Just inspect the seller’s reputation and make sure there’s some form of buyer protection.
Buying used isn’t automatically risky, but you need a way to confirm the part works. If the seller can’t show it operating and you have no return protection, I’d avoid the purchase. GPUs deserve the most scrutiny because they may have been heavily used, overheated, or physically damaged. CPUs and memory are typically safer, while a prebuilt can simplify support but may cost more or include weaker components than a carefully chosen custom build.
Set your total budget first, then compare complete new and used systems rather than focusing on one part in isolation. Sometimes a current midrange GPU bought new is a better overall choice than an older high-end card with no warranty. If you’re nervous, you could start with an inexpensive test build or have a local shop assemble and test the system, then upgrade the graphics card later.

RAM is often especially attractive used because it tends to be inexpensive and doesn’t usually fail without warning, but I’d still run a memory test once the system is assembled.
