Altough, the card performs pretty decent when compared to integrated graphics it is still highly priced and a GTX 1050 priced 25 dollars more than the 550 is better card to get right now.

$25 is some 30% of this card's price. It would be strange if GTX 1050 wasn't a better card if you need to pay that much more.

Hilbert you noted the the card uses 100 watts but looking at the graph it shows that the system at idle was at 50 watts already so the card probably consumes around 60/70 which would make more sense considering it has only 512 shaders.
