Is gaming on a 60Hz (5ms) TV sufficient?

I'm looking into a new TV, but am curious how fast it should be if I want to go online. I currently have a 60Hz (8ms) TV, and it has worked fine with games like Killzone 2 online. However, for some reason every now and then, the TV loses the signal. I don't know whether this is due to the refresh rate or the HDMI cable. So basically, do I need a 120Hz TV, or is 60Hz good enough?

Or even better like a new LG with 250 (I think) of Tru Motion Tech. Wrap your mind around that.

sounds good to me

but i dont understand tv's much:P

Only reason I could see someone wanting a 120hz+ refresh rate would be if you are really looking forward to the 3D glasses thing various companies are planning and actually think it will come out before you buy another TV.

most current games barely even render at 60hz. Sounds like a cable issue. The only reason I could see needing a 120hz TV for gaming is if you wanted to display at 1080i, but if you could use 1080p why would you use interlaced?

Ok, thanks to everyone. :)
