IMO, those speed they offer aren't worth the gaming you'll be playing. If you play those 3 games simultaneously, you'll probably ping high or lag with wireless connection being unreliable sometime. Upload speed are probably lower or symmetrical, meaning it's the same as the download speed if they don't list it.
Mainly those connection are probably only good for Internet browsing, emailing and etc. If this is the fastest connection you can get in your area, I suggest you ask around first, call them, talk to other customers who have the service, etc. First take a look at their Terms of Service and contract, because you want to jet the **** out of there if the service sucks without paying a terminated fee.
