Confused Between Buying 15" rMBP with Dedicated GPU or Integrated ?

Question

Hi Guys,
I am planning to buy my first ever Retina Macbook Pro 15 Inch.  And I need some suggestions, It is my first ever Mac Book in my life so I am pretty excited and anxious about it. But I am in a dilemma should I go for the Dedicated Graphic Card Model or Should I go for the Integrated Graphic Model. No, It is not for the Extra Storage Space on the SSD that I am contemplating to buy the Dedicated Graphic Card Model but more for the Dedicated Graphic Card.
I am gonna be using this for my Personal Use Heavy Web Surfing, Lots of Flash Video watching, Movies, Music, Occasional Gaming (I am not a Gaming Freak) But I do occasionally like to play some most talked about, popular game so I don’t want my machine to restrain me for any reason. So this is my Requirement.
Now I have heard stories about the Dedicated GPU Model which is not good as in firstly I will tell you what my experience is I used to have a Sony Vaio till sometime back with a NVIDIA Dedicated 128 MB Graphic Card, after using it well for 5 and half years one fine day it failed, and subsequently it also corrupted the Display and wont let the OS Boot up. When I took it to the service guys they said, this is a very common phenomenon that we are coming across with Machine which Have NVIDIA Graphic Cards, apparently they seem to be running some problems NVIDIA doesn’t seem to making it well in terms of longevity. Steer Clear from Machines which use it. So what even if it is the Famous Macbook.
If I am spending this amount of money I am atleast looking for the MAC to be going for till about atleast 6-7 Years. And there is where my apprehension comes in the words of my service guys that Please stay away from NVIDIA Enabled Machine if you can.
I have heard some guys tell me that well, even though modern GPUs run much cooler than before. It's just that there's been a lot of failures with dedicated GPUs in the past and there have been seldom a failure with integrated graphics. If you want your machine to last a long time,  We would recommend the Iris Pro one over the 750M one. You don't need to spend the extra on the 750M model. It's not going to benefit you. For most things, the Iris Pro performs the same as the 750M.
As far as gaming is concerned, one can play any game the 750M can, but may have to lower a couple of settings for some of them. If the DGPU failed, it would do exactly what happened with the Vaio. No reason really to assume that's going to happen but it is very much possible with a DGPU Model. The Iris Pro model is far less likely to fail in that way.
Before Iris Pro, One would have been against Intel graphics as they were too slow. Iris Pro is the first Intel graphics chip to hold up against dedicated GPUs.
It's important to remember that some of the NVidia GPUs from 2008 were defective, mostly the 8600M but some 9600M too. If you have a Retina Macbook Pro with a dedicated GPU, that's more likely to be problematic than Intel's integrated graphics. There have been hardly any issues with integrated graphics chips dying
Dedicated GPUs tend to be more powerful but they've always been less reliable. That's not to say they all fail, they just happen to have a higher rate of failure.
8600M, 9600M, 6970M, 6750M, 6490M, X1900XT, X1600, I think some old 7500 or 9200 too, all had issues.
I've never heard of an integrated graphics failure.
In the near future, Integrated graphics would be a better option for most people. Iris Pro is very close to the 650M/750M.
These are the comments that I have heard so far about the DGPU model Peter ? What do you guys think ? what would you guys advise me ?
Thanks !

Graphically intensive applications such as games. Some applications will turn it on just to improve graphic performance such as iPhoto. Having a dedicated card will have a higher resale value just because it has more hardware and better specs because of the additional card.
