60Hz vs 50hz. Does it matter?

I don't believe 50hz TV's exist anymore. Probably a typo.

In North America, they never existed. In UK/Europe, that is the standard. No typo.

I can't read, must be too early in the day. Sorry. :'(

Let me put it like this, the faster the Panel/TV, the better for gaming. Now faster doesn't always mean better picture, just less tearing in fast scenes
But yeah, 50 Hz are normal here, your Xbox is now also running with 50 Hz

tearing has nothing to do with how fast or slow a TV's processing is...input lag does...

In the USA it is 60hz, 120hz, 240hz.
In Europe it is 50hz, 100hz, 200hz.
refresh rate
http://en.wikipedia.org/wiki/Refresh_rate

american SD (NTSC) is 480i/480p, european SD (PAL) is 576i/576p.

To make it short: Hz above 60 make no difference at all...gaming is as smooth at 50Hz as is at 60Hz, because both are above the threshold where motion becomes smooth to the human visual system...higher refreshes are at display only, not source, and are artificially generated/interpolated by the TV, resulting only in less motion blur, but also interpolation artifacts and errors and increase in input lag, due to which most game modes in TVs deactivate high refresh rates anyway...

P.S. my sparks are a bit slow to fire so here goes the final verdict...all European TVs support both 50 and 60Hz input so the OP can buy any European TV, the US Xbox will work in native 60Hz on a European TV...
