Can you please give me some things to look out for? I'm building my first ever gaming pc and don't know how to verify a good working second hand GPU. Thanks

Ask the guy if you can do cash on collection. If he gives you an address different to the location of the listing then get the hell out.

Ask if you can bring your PC along (+ monitor) to test if it's working.

NEVER do Paypal friends and family. Always do goods and services no matter what.

If he says anything along the lines of "got other people asking to buy it, can send it to you first if you transfer the money asap" then it's bullshit scam pressure sale tactics.

All just common sense really.
