It'll work for you but it won't be that great. Mine is only slightly faster than yours. It runs at about .80 where yours is .57. It lags in MW2 quite a bit. I moved a little over a year ago and at that time my internet speed was about 7 or 8 mbps. I was pretty good at cod4 until I moved. Because your internet is slower, things don't register as quickly. So, you'll think you're killing a guy in MW2 because that's what you see on your screen, but you'll be the one ending up getting killed. In the killcam it shows the other guy shooting way before I start shooting.
So, it'll work but it can be frustrating when you use a full clip to kill a guy and he ends up killing you. You'll learn to adjust though. It'll be tough to connect to many friends online also. Oh, I'm assuming you're talking about using the internet for MW2. My bad if you're not.
Yes, ping is important. Mine runs anywhere from 1 - 1.50 ms. That's pretty slow like yours.
