Product review (3 stars): GE GDWT668VSS
I researched dishwashers like crazy and decided that I would just go with the same "updated" model of GE. Prices compared, it is about the same.
I had several things that I wanted. One was the potential for the same length of a normal wash cycle (114 minutes with added heat).  Secondly, I wanted hard food disposal and loading flex. I'm very easy to please.

All the newer models available had a little of this, a little of that. And the cycles were torturous in length because new and eco friendly uses less water and energy. It does not appear by reviews to help with cleanliness. In as much as the specs for the motor in this machine(GDWT 668) are the same as my old machine,(PDW 8480) the features do not work the same.

The positives, thus far, are that the dishes are shinier than I remember and the glassware sparkles! It does run more quiet than the old DW. The decibel level went from 53 to 52. And, as the new dishwasher only came with a pittance of insulation, I took my old insulation which wrapped the entire machine and re-used it, so this surely adds to the sound barrier. The dishes are clean, yes, and it runs quiet...but there are negatives in general.

The basket lay-outs have changed and actually gotten smaller. Most machines I researched did not have fold down tines and I wanted this feature. I have folding tines in the lower rack, but it doesn't help to improve loading capability like the old DW.  I have a large fry pan that I was able to load upright on the side. Now, it won't fit with the tine placement and if I put the tines down, there is no support to keep the pan upright and save loading space for seven peoples dirty dishes. I cannot fit two rows of coffee cups easily on the top basket, either and I could before. Again, smaller features. I was going to try and take the old lower basket and use it, but it's larger, sadly. I'll get used to it.

The silverware basket has a lovely cover system of holes that makes it so each piece can be cleaned without nesting. Frankly, if I had that kind of time, I would do without a darn DW, so I don't use it!

The final thing is that the added heat and drying do not work the same at all. The Manufacturer recommends Jet Dry. So, because it came with, I am using it. That being said, I have not opened any load of dishes to find them dry, glasses and mugs in particular. Nor is the door of the DW completely dry as with my old PDW8480. It's quite annoying, but not a deal breaker. I am not going to uninstall the darn thing because it sucks at drying stuff. I'll just be grabbing a towel and be glad it's all I've got to do!

I just hope that paying the $819.00 will last me 7 more years. I don't agree with any of the eco friendly technologies because in reading reviews, those people are paying more for less all the way around, with the exception of emotional comfort that they are helping to save the environs. This is why I chose the near identical DW hoping to get the same work out of it. I am practical and what works for me, may not work for others. Nothing is perfect, so it gets 3 stars. It cleans well, is quiet, and looks count.
