I doubt there's a need, as already stated:


But we were talking about i5 dual core vs i7 quad core then. Now i am just asking about i5 dual core, I have been doing a bit of research and it seems the 2.8GHz is about 6-9% faster than the 2.6GHz processor. Not sure if thats worth the extra, might not be any difference in real world terms.

Well, I can give you a perspective: GeekBench 3 scores. In real life, 2.6 GHz is just as fast as 2.8 GHz on GeekBench 3.

See 2.6 vs 2.8 GHz: http://browser.primatelabs.com/geekbench3/compare/1832333?baseline=1831465

You might be disappointed though that an i5 Surface Pro 3 can get very close to their scores despite clocking in only @ 1.9 GHz:

SP3 vs 2.8:

SP3 vs 2.6:

But then a 15" rmbp @ 2.2 GHz will double or almost double the scores:

Your pick if you want a 13" or 15" considering the CPU and memory performance.

You would benefit more by upping the SSD from 128 to 256 GB.
 
It would just be simple stuff like iPhoto, iTunes, email and web browsing. I am just trying to work out if by buying the 15" rMBP i might actually be buying a slower machine for what i am doing.
I see your predicament. Especially iPhoto is a very demanding app.
Just to be sure you should get the 15" with dgpu and then upgrade the cpu to max i7.
That way your email and webbrowser can utilize the i7s hyperthreading and larger lcache.

Don't be silly, that will be nowhere near powerful enough, I'm going to need a-

Mac Pro 3.5GHz 6-Core Intel Xeon E5 processor
16GB 1866MHz DDR3 ECC memory
Dual AMD FirePro D500 with 3GB GDDR5 VRAM

But i think i might need to go for a few of the optional upgrades to get a bit more power.

They are very cheap as well, i might get 3 and see if i can link them up.

What do you think.

You might as well as get the ones with 12-core E5-2697 v2 and D700, plus 64GB ECC RAM.

I think I liked the old Meister better.

6-9% between notebooks is meaningless. If someone wasn't sure whether one would be fast enough, I would suggest a 15" instead. In your case I don't think anything would make a difference unless you have enough stuff open to saturate the ram.

Your post may be sarcasm, but a lot of people on here really do suggest upgrades that provide very little value.
 
I don't suppose anyone can actually answer my question accurately, because it is unlikely that anyone has owned both 2.6 and 2.8 i5 and compare them side-by-side. I am just trying to work out whether the 2.8 GHz would be faster than the 2.6 GHz in general day to day use, like just switching between apps and opening and closing programmes, will it just generally feel snapper as it is running at a higher clock speed, or will the extra 0.2GHz not come into play until it is doing more demanding tasks.

I hope i am explaining myself properly, will it feel quicker is what i am trying to say.
 
Well i changed my mind again, i have just ordered a 15" rMBP, will be getting delivered Thursday.

I decided if i don't go for the 15" now i will be forever wondering what it is like to own one, so i decided it was worth the extra and went for it.

I know its is way more powerful than what i need for my usage, but its the only way i can own a 15". At least it will be well future proofed and I will not need to upgrade for quite a while, and there will be plenty of extra power incase my usage does change, who knows what i may want to do with it in the future. I quite like the thought of owning an i7 Quad Core, 256gb PCIe SSD, 16gb Ram and Pro Graphics, all sound really good.

Will let you know how i get on with it.
 
Just a quick update.

I have had the 15" rMBP for 2 days now and i am extremely happy with it, i am so glad i went for the 15" now as i am really enjoying having the larger screen. I don't think i will ever go back to a 13" again unless portability was a factor, but this laptop hardly ever leaves the house so i can't see that being the case.

Even though the 15" was £500 dearer than the 13" i still think it was worth it (just). The screen is beautiful and i seem to do a lot less scrolling now, and it is about the same weight as my 13" cMBP, but it feels lighter because it is bigger (if that makes sense).

I am quite amazed how thin and light Apple have made this laptop, also the speakers are pretty good as well, much better than the 13" speakers. It took me quite a while to make he decision of which one to go for, but i think i made the right decision in the end, even if it does make me feel sick everytime i think about how much i paid for it.
