I recently purchased a dell dimension e510 which I intended on useing for extreme gaming. I was a bit surprised when I got xp media center with it. I was always under the impression that pro was better for gaming? I have an old copy of xp pro but when I install it its very hard to get all my hardware set up. The media edition detects all of them fine. My questions is this; Is there really that much of a difference in pro and media center as far as extreme gaming is concerded? I plan on extreme gaming and need the best performance as possible. How much of a difference would it make if I used media editon instead of pro? Thanks
