If your board has the extra slots, another 4 gb won't hurt. I got some patriot 1333 2x4 gb for only $23.50 after rebate at newegg, and I spent the rebate card on food. Wait for black friday if you can. Extra ram always helps, but mostly for video work. Frys had 4 sticks of 4 gb 1600 recently for only $75.
