I was REALLY debating between the 2gb and 4gb version of the card.. A friend told me I shouldn't need the 4gb,and from the reviews he read, it's overkill, but me, I always like to get the best I can.
This works great, period; So easy to setup; Runs every game I've played at awesome FPS; I'm not a huge gamer, but I wanted something that will be able to handle that ones that I do enjoy well; Especially games like Call of Duty where detail can be crucial.
So far I haven't had any cons to this card; The only thing I could say is the size is a bit large; You will want to make sure it will fit in your case before you order! I had to move one of my hard drives to another bay because the card was hitting the plugs in my one hard drive and it wouldn't fit...
