here's an idea. say BF4 (i play this one), in the battlelog (i think you can go there even if you dont own the game), there you can search for servers, and you will see what ping you have on those. just filter those that are near you.
if that is not possible, then find a way to look for server ip addresses, ping them using cmd like "ping -t [ip add]". i forgot the site where there are a list of server ip's for tons of games.
this way you will have an idea. as for the bandwidth, it should be ok, internet is so damn slow from where i am, far from what the other countries have. i only have 2mbps lol
