That's the big question. I am going to order a Lenovo 470 and you can get it with either a GeForce GT 550M or a AMD Radeon HD 7690 1GB. I know the ATI (yes ATI) card is better and this will be used mostly for gaming. But what about when you switch them off and just use the onboard crap, is it Big a difference? ATI drivers still in the toilet?

AMD drivers are fine as long as you don't use OpenGL. Nvidia has better drivers, yes, but it's like comparing a Toyota to a Lexus. Both will get the job done but one has more features than the other.
So you should get the 7690 because of the extra gaming performance. -
Therefore the y470 graphics > y570 graphics.
hahhahaha thats awwwesome, with the kbl speakers this is quite the little mutimedia laptop
If only the y470 would at least have a 900p screen, 720p is too small nowdays for a 14 incher.
very interesting find, i didnt know
also, according to http://www.laptopreviews.com/lenovo-ideapad-y480-and-y580-specs-announced-2012-01
the y480 will have a gt650m while the y580 will have a gtx660.
Assuming the gt660m will be a rebadged 550m, this also means y470>y480 also. ALthough since the gt 635m is already a rebadged gt555m, its hard to beleive that the gt 660m will be weaker than a gt 635m -
The one in the Lenovo is much worse than this one though and should be avoided in general. -
There are several different flavours of the GT555m ( more info here) so it depends which GT555m you're comparing the 7690m against. For some GT555m cards the 7690 will beat handily, some it will get beaten instead.
-
the gddr5 version of the gt555m is in pair with the 6770m, and the 7690 is about 8-10% faster than the 6770m so yeah the HD card is the better option

I don't think anybody has the Y470P yet with Radeon 7690M to test it out. We really don't know for sure the factory clocks and a specific version of that card. Nobody knows for sure that it will identical to the ones in HP DV6 and Envy models. It should beat Y570 in benchmarks and hopefully in game performance as well.
Different GT 555M have also different factory clocks. For example a 128bit Asus N55SF and MSI GE620DX will beat 192bit Dell XPS 17/M14x because of the higher stock clocks. So if you don't plan to overclock or don't know how to, N55SF might actually be better for gaming despite having a limited version of the card.
Here is the breakdown on GT 555M:
144 cores 709MHz (GF106), 128Bit GDDR5, e.g. MSI GX780
144 cores 590MHz (GF106), 192Bit DDR3, e.g. Dell XPS 17, Alienware M14x
144 cores 590MHz (GF106), 128Bit DDR3, e.g. Schenker XMG A501 / A701 (Clevo W150HRM / W170HN)
96 cores 753MHz (GF108), 128Bit GDDR5, e.g. Lenovo Y570p / Y560p
144 cores 525 MHz (GF116), 128 Bit DDR3, e.g. Medion Akoya P6812, LG P330, Asus N55SF (675Mhz)
I think Asus N55SF has a higher core clock speed by default, which results in the best stock performance out of the entire group. However, all of those can be overlocked and I assume M14x with Dell XPS 17 will come out on top when overclocked thanks to 192 bit architecture. Then it will be Clevo W150HR/LG P330 and others, followed by Y570 in the last place since it has basically a modified GT 550M card. The difference is not huge, but it will probably result in 3-5 fps in the end.
Asus N55SF vs Alienware M14x/XPS 17:

1. The 144, 128-bit GDDR5 version never existed, outside of a prototype model. Too bad, because it would've been the ultimate 555M by a mile.
2. The 192-bit DDR3 version walks over the others. There's no reason to recommend a different variant.
3. This is way tangential to the OP's original question.
Radeon 7690 or GeForce 550M
