[arvindlal1301]

Looking for two things #1 and #2 can give separate answers
#1 best LAPTOP processor for the job in the give price range.(u can suggest another processor with the same price range.)
#2 best laptop in terms of the upgrade -means add some ram machine goes faster ,remove hdd add ssd if possible.
#not at all concerned about display that is HD display or graphics.
# use java programming -IDE,DB(oracle/mysql) and a web/app server to test the application.

presently using - CORE I7 4600U,256gb ssd,8gb ram, doing decent job sometimes gets too slow need new processor.
