If this the one you have?
Newegg.com - lenovo G780 (21823LU) Notebook Intel Core i5 3210M(2.50GHz) 17.3" 4GB Memory DDR3 1333 500GB HDD 5400rpm DVD±R/RW NVIDIA GeForce GT 630M
If so it has a slow 5400RPM hard drive. 7200RPM or a SSD would make a big difference in performance. 4GB ram should be okay.
