Hello, I have the i7 variant of your laptop. First of all the graphics card is not that bad, you can handle almost all games, at least on minimum. Sadly you cannot upgrade the processor to i7. The laptop was built to supply certain power to your cpu. The i7 is not only more power hungry, but also a different architecture. (i7 Quad Core vs i5 Dual Core). It depends on what you want. I upgaded my laptop to SSD, and that totally changes your performance. It will make booting much faster. But for gaming, you will need a new laptop, or drop the graphics to minimum. Good luck!
