I'm new to choosing PC parts, although I'm comfortable assembling a computer. My budget is roughly $600 USD, or about $800 CAD, and I already own the monitor and other peripherals. I'd like to play BeamNG, Peak, and GTA 5 at 1440p. I'm open to buying used parts or a used complete system, and I'd prefer an Nvidia graphics card if one fits the budget. What parts or systems should I look for?

A sensible low-cost platform would be AM4: a Ryzen 5 5600 or 5600X, B550 motherboard, 16GB of DDR4, and a used RTX 3060, RTX 2070, or similar card. An RX 6600 is also worth considering if you find one cheaply. Add a reliable 650W power supply and a basic case, but expect the final total to be near or above your budget.
You may need to save a little more for comfortable 1440p performance. A used AM4/DDR4 build is probably the best target, since newer DDR5 platforms consume too much of the budget. Watch for bundle or open-box deals, compare expected game performance before purchasing, and be patient rather than forcing a poor new-part build.
I’d start by searching locally for a complete used PC with at least a Ryzen 5 5600-class processor, 16GB RAM, and an RTX 3060, RTX 3060 Ti, RTX 3070, or comparable GPU. A tower without a graphics card can also be a good deal if you find the GPU separately. Test the system, check temperatures, and verify the power supply before buying.
At this budget, a completely new 1440p gaming PC—especially one with Nvidia graphics—will be extremely difficult. Used parts or a complete used tower will usually offer much better performance per dollar. Be flexible about the GPU brand and prioritize the strongest graphics card you can find.
