hey guys.
next week im going to buy a new video card.
which i cant tell yet, because i have still many questions.

1. which cards should i consider to buy?
i noticed, that there are some cards, which have less vram than others, but are more expensive than the "faster" ones....so on which properties should i focus except vram?

2.can i buy every video card i want, without having to worry about compatibility with other hardware on my system?or do i have to look which motherboard(for example) i have and which cards fit on it?

3.as you certainly already noticed due to the first to questions and the headline, im totally clueless when its about computer hardware....so here is my third question....
is it easy to install video cards(not the drivers but the card itself)?
or is there any know how necessary to remove the old one, and insert the new one?


thx for the answers in advance!
