Bought a new MBPwoTB. Got 2.4 i7... worth the $300?

With all the battery life and graphics glitches of the TB models, I went with the nonTB version.

I was worried about the lower TDB proc but it looks ok in real life usage.

I came across a good deal (I wanted space grey but I felt this was a good price)

You hardly see discounts on 16GB on CTO processor upgrades and only minor with edu. For $200 off and no tax + free shipping and future proofing with 16GB was a no brainier.

However, I am not sure what I am getting with the 2.4 i7 vs 2.0 i5. Yeah I know the frequency is higher but some questions:

• Will it throttle more often?
• Will it impact battery life?
• How much faster is it than the 2.0?
• Will it be warmer to use compared to the 2.0?
• Is there anything else I gain with the i7?

 

Thats not bad at all. Seems like around a 25% increase in price and 21% increase in performance in that specific task.

edit: why not keep the 16GB ram?
