Need advice on GPU : New RMBP or late 2011 MBP ?

my only choice to move on from :

Core i7 2.2Ghz - 8Gb Ram - 750Gb HD - Ati 6750M 1Gb GDDR5 (overclocked to 800/1000Mhz via ati tray tools)

is the GPU.

So how really a Geforce Gt650M compares to the Ati 6750M/6770M ?

in Starcraft 2 under win7 x64 i get a steady 60fps to 35fps in Ultra settings.

That would be the only reason for me to upgrade if i can get much much more fps.

Thanks for your input:)

P.S : what could be a good price i could sell my current machine ?
 
The GT 650M is around 50% more powerful.

However if you plan to play at 2880x1800 resolution, you will get much, much poorer FPS as compared to the late 2011 MBP. My advise would be to go for the non-retina MBP for gaming.

As a starting point, you can check Mac2Sell, eBay, or Amazon for prices of similar models, to get an idea of what you may be able to charge. Then adjust your price to account for condition, configuration, remaining AppleCare coverage (if any), etc.

It's on average 50% more powerful at any resolution. Why you have to ask the wizards at nvidia.

And why should he not get a retina for gaming? He can just turn down the resolution to 1440x900 and it will perform identical to the non retina MBP.

Have you seen how awful and blurry non-retina applications look on the iPhone 4? I worry that the RMBP will face the same problem.

However I'm willing to wait a few more days for other people to review how well it scales. Will it looks fine, or will it face the same problem that the iPhone 4 did.
 
iPhone4 can't change resolutions, why would you compare a phone to a laptop? Anandtech already has a small review on the screen and he says it looks better at 1440x900 than the previous MBP due to the quality of the IPS screen.

Because the iPhone 4 has a 960x640 screen that tries to run an application at 480x320 resolution? Isn't that the same thing as taking a 2880x1800 screen and running things at 1440x900? Regardless of whether it's a phone or a laptop, it's still an LCD display attempting to display pixels.

Anyway that review you mentioned sounds interesting. Any link to it?

Because the iphone will blow up that smaller image to fit the bigger screen, thus it will look blurry. The MBP will change resolution on the screen, using 4 pixels to represent 1 pixel, giving it a perfect ratio, thus it will not be blurry at all.

You realise that's the same thing, right? The iPhone resolution is double that of the old one (the screen is still the same physical size), the same as the new MBP is double the resolution of the old one, so any scaling will be done in a very similar way.
Now, iphone games on an ipad, they look pretty dreadful.
 
First of all it's 4 times the resolution.
Second it's far from the same, as in the iphone case, the lower resolution image is stretched to fill the higher resolution screen. While on the laptop you can have everything rendered to the same resolution you run the display, so there will be no stretching.

If the iphone was able to change resolution to the 480x320 or whatever was used in the example earlier, the image would appear more crisp than if stretched to fill a 960x640 screen.
Hope that makes sense, but if it doesn't; just stop worrying and just take the word of professionals like anandtech who says 1440x900 looks great on the retina.
