I am in the process of purchasing a new laptop that I will be using for gaming, video editing, and basic school work. I'd like my budget to remain in the 1000 dollar price mark, as I see few options available.
1_Depends on the game,in some games that benefit from the extra cores(like some RTS games),i7 would be better, but in other games(mostly FPS type),the difference isn't noticeable
2_GTX 260M with a C2D CPU will perform better than a GT360M with an i5 CPU in gaming.
Well for strictly gaming,i would recommend going with the faster VGA,because for gaming is more important to have a better VGA than having a better PSU.
I myself,would buy none of them,and instead i would pay about $200 more and get the ASUS G73 which has an i7 720QM with a 5870M.Its completely worth the extra money.
