I think I am right in saying , it's not having a super duper ,card that makes the difference , it is the monitor , afterall that's what you look at. If it isn't set right , then it doesn't matter what is being sent to it !
Think of your TV , a programme could be recorded on the best cameras in the world, if you have a cheap old ,nasty , TV , then you are going to see a mess.
Also , don't forget those big round things in your head , if they aren't tested , then you might not even see the screen.
