GeForce 3 Ti200 vs GeForce FX 5200

I want to upgrade my video card from a GeForce 3 Ti200 to a GeForce FX 5200
but f*cking nvidia uses different terminology on each description of the
card so that I will have no way in hell of comparing them except for the
differences in bandwidth. I know that the GeForce 3 Ti200 has a maximum
bandwidth of 6.4GB/sec vs. the GeForce Fx 5200 at 10.4GB/sec. Now, I am
thinking that the extra bandwidth difference alone is enough to warrant this
small upgrade considering the GeForce FX 5200 I am looking at is only
$89.99. Is my thinking correct? And last of all, what the hell is an
integrated TV tuner. If it's something I can hook up my cable tv up too and
record movies/shows to hard drive cool. If its just a fancy way of saying it
has TV-OUT, big f*cking deal. Thanks for all comments.
