I'm going full frame Currently have the D90, the only investment i have in dx lenses is a Tokina 11-16...soooo my question is will I notice much difference between the 800 and the 800e? Photography wise the only thing really floating my boat is nightscapes, with the occasional long exposure during the day, have yet to decide if I will go for the 14-24 nikon lens or a third party one, the 14-24 is mighty sharp.

I suppose what I am asking is whether for me the new hobbyist for those who know will the 800e be much better resolution wise than the 800 bearing in mind we are talking night shooting, stars etc etc, also upgrading my computer, am I right in assuming that 32gb ram, 3 gb dedicated graphics card, 256gb ssd, and a i7 2.4gz processor will be more than adequate for CS6 + LR and some gaming?

I know its a huge leap from the d90 but I have a once in a lifetime ( at this stage) opportunity to upgrade so thinking do it once, do it right.. any thoughts?

Thanks
