How much better is Blue Ray?

[caduceus]

I have currently got a Toshiba 32WL56P LCD tv, and a Sony RDR GX210 DVD player. And I was wondering how much better a Blue Ray player is than the standard player I have right now. Is the difference enough to justify the cost?
I don't watch alot of tv, just TopGear, Holby & the news tbh. So not bothered about the grainy delivery on that front. But would like to enjoy DVDs in a more superior quality.
Is the tv I've got good enough to keep, and upgrade to a blue ray? Or do I need to start thinking about newer technology to make use of a new B/R player?

Thanks

I think the only reason I bring up the quality issue is because the difference between normal tv and Hi Def is astonishing.

Is the difference between normal DVD and Blue Ray not the same kind of step up in performance?

Btw, I currently sit 3 meters away from my 32 inch LCD.

Thanks for the replies so far gents.

Thanks very much for all the comments guys! Very informative.
I went into a hifi shop today for a quick nose around and had a gander at some B/R players. The guy in there said if my tv wasn't 100 htz or more, then don't bother. He showed me a 50 and a 200 htz and the difference was stunning.
At the moment I'm using a component lead from the DVD to TV, as I don't have an RGB port. Only a HMDI port and the usual comp and scarts.

Also the consensus on here seems to point to not bothering with my current setup. So if the tv is less than a 100 anyway, I don't think I'll bother for the time being.

Cheers again.
