I have a Dell Inspiron 15r laptop that i bought for mobile gaming when i'm not at home. The problem is it only has Intel integrated graphics, and I am told I need a dedicated card to play games. I checked out the Dell site and some of the 15r models come with ATI cards, but other than this what video cards will work with my laptop? I like Action/Adventure, RPG, MMORPG (WoW anyone?), FPS, etc., so I want as good of graphics as possible with my computer. If you need any other specific info please tell me where to find it as i'm not a whiz with computers and especially laptops.
