How can I know amount cap for cards?
Are you talking about caps in the deck? The answer to that is: Silvers/Golds only get one copy. You can have 6 silvers total. 4 Golds total. 3 per Bronze card.
If you're talking about limits on the number of cards in your collection, the game will not allow you to craft more than 3, because that's the limit on repeat cards. Your collection will go up by 1 if you unlock that card in a certain way, allowing you redeem extra cards for currency.
Type of version (PC vs Console) does not matter, all Gwent is played the same.
