I am looking at gettting my first Mac for programming, photoshop, occasional light gaming and video editing. I am wondering which of these would be better:

13-inch: 2.9 GHz
2.9GHz dual-core Intel Core i7
Turbo Boost up to 3.6GHz
8GB 1600MHz memory
128GB SSD
Intel HD Graphics 4000
Built-in battery (7 hours)2

or

2.3GHz quad-core Intel Core i7
Turbo Boost up to 3.3GHz
8GB 1600MHz memory
256GB flash storage1
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory
Built-in battery (7 hours)2

Also what does 'Turbo Boost' mean.
Thanks

Turbo boost is just automatic overclocking really, trying to get most performance out of the power/thermal envelope.

What's more powerful will depend on how often your workload uses 4 cores.

The second one is much more powerful. The quad core processor and most importantly the dedicated graphics card are big performance increases over the 13" Macbook Pro.

The Turbo Boost means that if you're using an application which only loads down one or two cores rather than all four, the processor can increase its clock speed to give you better performance.
