Hi guys, another internet connection question. What do you think about a 5mbps connection but with 15gb monthly limit?

I am currently using 2mbps broadband connection and as far as I know, no monthly usage limit. These two has same monthly bill price of 999.00 PHP. Although 2mbps is good enough here, I just want to try it out but first asking about your opinions.

What I usually use:
-Facebook (always online when using laptop)
-mostly Online Gaming
-browsing websites
-a little youtube
-occasional movie and music downloads (I think this one would be easy to monitor according to file size. Right?)

So do you think a 15gb monthly limit would be enough or not?
If in case there is a TWO of me, would it still be enough?

Thanks. Waiting for your response.

If you're gaming online I'd suggest you get as usage limit as possible, it might be easy to reach your limit, especially if there are a few people using the same connection.
