2 things... first @ Isabella, Yes during games it will be plugged in- otherwise in classes it wont be plugged in...
second thing... I've found a third system:
#3) Gateway 15.6''
-Intel Core i3-330M
- 4GB DDR3 RAM
- ATI Mobility Radeon HD 5650, 1 GB
So only reason i thought this might be in is because the graphics card is better... but is it worth lowering to an Core i3?
Definitely go for this one,HD 5650 is mile ahead of GT 230M/HD 5470M in games
