The words Gaming and laptop are two things that should in no way be linked.
If your going for gaming, get a desktop. If you want to be mobile, dont play games, or lower the graphics. Believe it or not, any more than 2 GB of RAM and a decent >2.2Ghz dual core is not needed to run games. My friend still plays games on an old single core 2.6, 1Gb of RAM, and a 8600GTS.
