just a suggestion about operating system,
i think u should go with windows 8,
why??
to save money!!
until the end of jan 2013 windows 8 has really low price,
and is is a lot more cheaper than win7.
u should definately check out the price in your country.
I have windows 8 too,
and it is not as bad as some people say it is, it is actually nice and very different than all the other windows.
and given that it is cheap until jan u should buy it
