Base model MBP sufficient for digital photography?

The other night I picked up the base model, late 2013 MBP (2.0 ghz i7, 256 gb ssdhd, 8 gb ram).

I am coming from a mid 2010 MBP (2.53 mghz i5) that still had some life, but really was not up to what I was asking it to do with the large raw files from my D800E. The late 2013 is like a speed demon in comparison!

However, I have a few questions:

While the size of the hard drive sucks compared to what I had, (750 gb), I can get around that by using external drives and the cloud.

Of more concern, is this. I was leaning towards the next model up with the discrete GPU and 16 gb of RAM, but was not really willing to part with the $$$$ to get those features. All I really will be using this for is light photoediting using Aperture, Capture1, and photoshop. Will this machine be sufficient for those tasks?

Thanks..

And as far as RAM is concerned 8 gb is enough for photoshop/aperture, etc/??

Thanks for all the replies.

After spending pretty much all day playing around with photos and having different apps open at the same time and really pushing this machine more than it would get used in my normal, day to day activities, I think 8 GB will be fine. I've never kept a laptop more than 3 years anyway, so "future proofing" is just dropping more money into it needlessly, and honestly, after spending over 2k with taxes for this computer, I am really not in any hurry to drop more $$ into it. It's easy to say "but it's "only" another $200.00 when it is not your money..

Coming from a 750 gb harddrive, going to 256 gb is a tough pill to swallow, but considering that "only" a little over 500 gb of that were being used, and of that 500 almost half were things that I either no longer needed or were things that could be archived, I think I will get along ok with 256 using a combination of external drives, network storage, and doing a better job of managing what programs and files I'll be saving. I'll also need to start thinking more about cloud based storage I guess...
