I have a Philips TV with 50hz, 2 to max. 4 games that I play and not really much time to gamble (probably 10-20) hours per week.
In my situation, should I buy the Series X (499.99 euro and with a drive) or the Series S (290.90 euro without a drive and with slightly weaker graphics performance)
That also depends on how many games you want to get yourself. The Series S has pretty little memory, and you can't save money on used games either.
And you won't always have the Philips TV, your next one will be a 4K TV one way or another because there's nothing else left. Then you can provit from the 4K resolution.
I would really only buy the Series S if you maybe play Fifa and something else every year and don't want to play in 4K.
1. My TV has 4k
2. Yeah haha fifa and play like gta and forza otherwise no
Then think about whether 1080p or 1440p is enough for you depending on the game.
I have several games myself and I also like to sell games that I no longer play. With that I have the surcharge back in pretty quickly.
And since you have a 4K TV, it would still be good if you buy the Series X.
