Yes, (G)DDR3 consumes equal or less power compared to GDD5. Power consumption primaly depens on which manufacturing process the chips are made on. 32nm consumes more power than 22nm and so on.

Okay, so are we in agreement that the GT 650M GDDR5 is best for 1080p and for resolutions lower than that the DDR3 memory would be a better option, for the price?

gddr5 would be better for anything >900p, imo.

DDR3 isn't better for anything, it just won't be as much of a bottleneck at 720p/768p.

If you look at the scores on the notebookcheck.net website for the 650m , i cannot really see that much of a difference between the GDDR3 and GDDR5 scores., in any benchmark.

I am currently interested in a cheap laptop with a GT650M, only downside, it has GDDR3 memory. It's a Medion with a i7-3610QM and lots of other very good stuff compared to other equally priced laptops. I was planning on playing games like GTA IV. Is GDDR3 really worse for gaming in the native 768 resolution?

I now notice DDR3 is being discussed, are GDDR3 and DDR3 the same thing?

[Baenwort]

They are not but in this case the difference is a typo as the GPUs don't use ddr3 but rather GDDR3.

At the native rez of 768p you will not see a difference that is not in the single digit percentages at that rez. The main advantage of GDDR5 is at 900p and higher resolution. If your gaming is typically done on a external monitor you may want a GDDR5 version but on such a low rez display the impact is not great.
