You see 60, due to the speed boost, it plays with the #'s a little.. over an extended period.. if you could do a speed test that say tested over 5 minutes.. would avarge then likely down to the 45.
Personally? For gaming... if its only YOU gaming (even maybe 2 people gaming).. no, i dont think you would see a major difference.
For gaming, it usually uses only a VERY SMALL amount of bandwidth at one time.
Biger things like ROUTING, PING TIMES, etc all take more an effect on the gaming that the overall speed of the connection.
Bigest area one would notice.. is if there are alot streaming (netflix, etc) at the same time, downloading, etc.
Yes, I'm well aware of how speed boost works. When I do speed tests, they usually start out being way over 100mbps, but they always end at almost exactly 60mbps. I've never seen anything below 60mbps and, when I download games from Steam, which sometimes takes a couple of hours depending on the size of the game, it consistenly shows between 55 and 60mbps. Steam servers occasionally run slightly slower, but not often. On Wi-Fi, I get about 25mbps on my iPhone 4S. I have the old SMCD3GN modem/router.
Well, its $10 less per month roughly..
(say roughly, as you will have to go up to the new hitron CGN3, so may be an increase on modem rental)
So you would be saving money, and have more potential speed. Might help overall.
Only thing is you would be taking a 30g / month drop in usage. IF your internet usage is under 120g each month, i dont see why not to switch.
(if you have home phone and TV as well, you may be able to get 200g usage for free anyways)
