Lord Of The Rings online Gold

I recently updated my PC and remembered reading about a high res client...I've looked into it a bit and seeing pictures from the high res client, it really doesn't look any different than the regular on ultra high settings...is there a worth while difference?

Also I find it odd that I wasn't finding many threads about the high res client since about 2008...has something happened to make the high res client no longer needed?

Just want to be sure I'm not downloading a second client with 10Gb + for no reason...not to mention the risk of breaking my current client.
