Hi, Im looking for a gaming/school laptop, not a mac though, I want it to run GTA IV on decent settings, as well as a few other games. I have a price range up to $1,000, I would like to have it weigh a reasonable amount around 4-6lbs. Also want it to be pretty fast and last probably for about 4 years. And if you could recommend a good brand that I should look. Thanks!
