Here is a fun idea, a blind test for PCs of various price points vs a console attached to both a montor and TV.
Various LTT people blind test games running on various systems trying to guess if they are running on a PC or PS5 (or xbsx).
The main question to be explored is how expensive of a pc can replicate the console experience.
The monitor and TV angle is useful because I think from far away a certain level of detail disappears so you can get away with more.
The systems should be:
a used low end pc - i5 3070, rx580, 16 gb ram, ssd (you can get that for like 150 eur)
a used "high end" pc - i7, 1080TI, 16 Gb ram, SSD (you can get that for like 220 eur)
a new 500 € pc - st with 6600xt (shjuld be about on par with ps5)
a used last gen pc - ryzen 3600, 3060TI, 16 GB ram, nvme (600 € ish)
a new mid tier pc - sth with 4070 for instance
a new highend pc - sth with 4090
These tiers are a bit random and ofc should be adjusted a bit.
Ideally, you would have all of these setups side by side in one room with controllers attached and people could walk from one to another and test them out and then give their assessment. Naturally, some people should be gamers, and others total casuals.
