Its all down to what packages are available to you in your area.
Like can you get Fibre, is it FTTC (Fibre To The Cabinet) or FTTP (Fibre To The Premises)
I am one of the lucky ones to be able to get FTTP (Infinity 4) with BT and I get the following ping to the BBC Site:
ping -4 bbc.co.uk

There are other people with other providers that have better pings than me.
I mostly get around 300Mbits down, but it does drop down in the evenings, but never drops below 200Mbits.
I have only had my speed drop down to about 45Mbits the once, but after phoning BT they resolve it and its been fine since.
Now, how is it for gaming?
Hmmm, that would depends where the online game is being hosted doesn't it.
I play online with US and EU friends, and I get about 160ms latency with my US friends which I think is good considering the distance, and I get about 7 to 9 ms latency with some EU (well UK based services) I get around 9ms latency on Blizzards World of Warcraft EU Servers and 140ms on their US Servers.
Those 140ms and 160ms latency might seem high but it depends on the type of game, but I use to play World of Warcraft on the US Server back when I only had 4Mbits ADSL 2+ connection and the latency used to be around 400ms and it was still playable.
Now how does this feel in the evenings, for me I have noticed the latency doesn't change at all.
I would also wait for other peoples comments before deciding.
