I need to test a graphic card in 30min

[No name.]

Im going to buy used ftw3 ultra 3080 10gb. I have 30min to run some test before I buy in my system. I downloaded 3D mark (timespy and fire strike for the tests) also I downloaded heaven, superposition and furmark. the guy that Im buying from have god of war. so what should I do? run god of war then plug gpu to my system and run timespy, fire strike, heaven and superposition? also how can I compare results in heaven and superposition since they dont have any compare option. That guy is selling 730 C$ so Im kind of suspicious for that much low price. He said that he is going to buy 4080 but I dont know how much I can trust.

Figure out the monitor size for the test and look up GOW results and run them the exact same. 
5 mins of furmark into a time spy run then play gow. Should be plenty to verify it matches the results you can look up beforehand.

Yeah, I would pretty much do this.

 

Just enough to make sure it actually runs properly and isn't doing anything it shouldn't, and then continue from there on my own.
