The next set of processors will start around the i5 speeds and go up. The i3 will be obsolete by summer. Unless you never use the computer, spending a little extra now on the processor and prolong the computers use will save in the long run.
Even if you get only 4GB of RAM, just add more later.
Edit: Lenovo is a good brand, too.
