Average System for All Around Laptop

[marvs2013]

I have a
L840 Toshiba Laptop with i5 3230M @2.60Ghz
with 2GB DDR3 SDRAM which i plan to upgrade to 6GB or 8GB?
AMD Radeon HD 7670M 2GB
with 640GB HDD

Is this good enough as an average performing laptop for all around use such as editing, gaming, working and other stuff?

Should I upgrade it to 6GB or 8GB RAM?

Thanks I can't really decide on my own, i'm not an expert with these kind of things.

Editing; If video, then yes, its ok.
Gaming; yes, but nothing serious like Battlefield 3.
Working; Yes!
Other stuff ....? Upgrade the RAM to 6GB; that should be okay.

Ok thanks. Haha I don't play serious stuff life BF3 hehe.
