I am a graduate student in computer science and my budget is around $1000 to $1200. I am looking for an efficient LENOVO laptop for my school and job. Most days I am working simultaneously in dreamviewer, eclips (with android sdk ! I hate to wait to run the android emulator for minutes) , wamp , word, excel, pdfs, have a database open, lots of tabs in my web browser, some video streaming or listening music and maybe editing an image in photoshop. Basically I want a GOOD performance! I want a fast one..that is why I don't care if it is a quad core or dual core. I guess the clockspeed is much more important. Does anybody have a good reccomendation ? cuz I really need it.. Thank u so much I will appreciate it if you can help me.
