What should i do to improve my desktop build? i only have $65 left.
I don't know if you can find it under 65, but Windows doesn't come with Office. You can get the processor for 288.39 at tiger direct (parts picker doesn't show the current sale price): http://www.tigerdirect.com/applications/SearchTools/search.asp?keywords=core+i7+BX80637I73770K
Buy more RAM.
