I'm planning a roughly $600 PC mainly for general everyday tasks and heavily modded Kerbal Space Program. Since the game can be very CPU-limited and may rely heavily on a single thread, I'm prioritizing a strong processor and at least 16 GB of RAM. The graphics card is less important, so I'm considering buying a used GTX 1080 for around $80. I have a Micro Center nearby and would like to use one of its CPU, motherboard, and RAM bundles if that lowers the total cost. The listed build comes to about $608 and includes a Ryzen 5 5500X3D, 16 GB of DDR4-3200 memory, a B550 motherboard, a 512 GB NVMe SSD, a 750 W power supply, and the used GTX 1080. I also found a used complete PC for $525 with the same CPU and memory but an RTX 3060 12 GB. It might save me around $100, and I could test it before buying. Would that used system be a better deal, and should I upgrade it to 32 GB of RAM?

The $525 used system with an RTX 3060 sounds like the stronger value, assuming it includes a usable SSD and a decent power supply. The 3060 is newer, has 12 GB of VRAM, and should outperform a GTX 1080 in many games while using less power. Being able to test the computer before paying is another advantage. Check the SSD capacity and health, confirm the system is stable under load, and ask what exact motherboard, power supply, and storage it has. Sixteen gigabytes is enough to start, but adding another matching 16 GB kit later would be sensible for heavily modded games and general multitasking.
Before comparing the totals, verify exactly what the Micro Center bundle contains. The listed price appears to be an adjusted estimate because the specific processor wasn’t available in the parts database. If the bundle really includes the CPU, motherboard, and memory for $170, it can make the new build worthwhile, but make sure the board and processor are actually compatible and that the board’s BIOS supports the chip.
The bundle is real and includes the CPU, motherboard, and RAM. I only adjusted the price in the parts list because the exact processor option wasn’t available there.

I’ll check whether the used system includes an SSD and inspect the other components before deciding. I was mainly unsure whether the extra 16 GB of RAM would be necessary right away.
