Frankly, I would be happy with A6X performance. MAMEReloaded 1.39 on my iPad 4 destroys my S3, Excite 7.7 and TF300. Not to mention others recent tablets tested, in spite of the iPad pushing a LOT more pixels. MAME is a very good app to test how powerful the actual CPU is.
If the Snap 600 is faster than the A6X, I will be happy.
Added: This of course assumes the new radio improves the weak 3G performance and battery sucking demon ways with low signal. Worse of any device I have owned or tested. Still, the S3 is my favorite. Call range is great, in spite of the data radio issue and I am mainly in decent 4G areas- but not always. I turn the data off in weaker areas to avoid battery drain when needed.
