260m sli vs 765m

processors quad core intel 2.1 with the 260m sli or I7 2.4 with 765m

I know the 765 will run games better but how much better. I can trade my old m17x for a new one with those specs and about $700

Is it worth it? opinions???

Well you have to understand your not just going to just a performance increase.. But it being a single card will run cooler, more efficiently and have far less energy draw.. http://www.notebookcheck.net/NVIDIA-GeForce-GTX-260M-SLI.18909.0.html You can do a direct comparison right there on the right side between the two..
