If 700 dollars is in your budget and you actually play PS5 games, it's a no brainer.
If you can't afford it, you can't afford it.
The best way to look at it is this. How much are you willing to pay for a GPU upgrade to your PS5?
If you are in the camp of "it's not a significant upgrade" then I'm sorry, you are trying to convince yourself, not us. It is, and nearly every relevant new game that comes out will be better on the Pro.
If you are of the "it may not receive support" camp then you don't understand how any of this works and you should kinda research a bit I think. Again this is wishful thinking.
The only argument against the Pro that really has any basis in truth is that you cannot afford it. I understand and that does suck. However, if Sony offered a GPU upgrade via software that did the same thing on vanilla PS5 for free, are you telling me you would not want the upgrade? Of course you would. Everyone who owns a ps5, and I mean everyone, wants a free gpu upgrade. They just don't want to pay for it.
Here you go:
She: What kind of woman do you think I am?
He: We’ve already established that. Now we’re just haggling over the price.
PS: Also "Sony charged too much" is an argument against Sony and not the Pro. You are mad at Sony. That said, the XSX with similar SSD size and no upgrades is not much cheaper, so I think if you honestly compare the hardware costs vs what you get, it isn't that much overpriced, but that is just my opinion and well unrelated to the Pro's performance while gaming, which is elite. Every day that goes by, every game that comes out, we will be getting more for our investment here. Each new game that is pro enhanced increases the value of the pro itself.
