I recently bought the 3L from the egg when it was cheaper than the 2L. So far it has been OCing quite nicely, currently at 1140/1300 with 1.25 V on GPU, not sure of memory voltage. I think I can go farther, but the version of trixx I got (was recommended to get the modded one from here) does not have an option to adjust memory voltage. Any help there?
With that aside, it is a really nice card. Now that the 2L is cheaper again, I would go with that though.
