I know here is for CPU and components, but my question here is just about the 3 different cpu and e respective motherboard. My usage is more for internet, work (lots of programs/windows to be opened at same time..programs like matlab, java, etc) and games like Football Manager type...maybe sports games like Winning Eleven as well.
Sincerely seeking advice on which is better to be purchased! Thanks!

Send me a PM. Pick out a newegg wish list and I will build it for you parts plus $100 labor and give you a 1 yr warranty and available 3yr warranty from squaretrade.

Heres a link to the last build i did for $650.
