Not at all, it's normal to advise people to temper their expectations. What is weird is going into all the PS5 threads and telling people to temper their expectations. Ain't nobody paying you for that shit.
With how often the hype train gets insanely out of control especially with new platforms, I really don't see an issue with his statements in each thread. It's not like there's one master thread for PS5 discussion and his posts are not off-topic for the threads he posts in.
Okay, so what? Both Nvidia and AMD have made poor products in the past (guessing you didn't own a 480) but Zen chiplets are an excellent choice for PS5 and it's a highly regarded product. We don't know much about Navi yet, but the leaks look much more promising than Vega did. There isn't an Nvidia or Intel architecture suitable for PS5. Meanwhile there are two new AMD architectures available and they're both seen as being some of AMD's best for quite some time
You talking about the GTX 480? You could've probably chosen the FX series for NVIDIA as an example because it was probably the worst thing NVIDIA has ever done lol.
All I remember the 480 being awful about is the heat and power consumption, but I was less involved online those days so I don't remember what the general consensus was.
