[Solved] GTX 460m vs. 470m vs. 560m (vs. 6970m)

Hello everyone, I'm thinking which one is best here: 460m, 560m or 470m. Planning to get Battlefield 3 when out. But for that I need to know which video card is the best. I'm planning to spend no more than, let's say, $1700, but for a quality laptop. I know that AMD is best for gaming, but still, PhysX won't let me go... And I like nVidia more. So, for a great and wonderful (and cheap) gaming laptop, I'm thinking somewhere like this:
Intel Core i7 2630 2 GHz
8 GB
GTX 470 (looks best for my case, though don't know the system requirements for BF3 yet (I don't think that even demo/beta will be out any time soon...) but it should hold at least 30 fps on 1920x1080, I think...)

By the way, what's the cheapest system builder? I mean, is it Sager, Cyberpower, Eurocom or any other?

6970M is much faster than the other 3 options.Its like
6970M>>>470M>560M>460M

By the way, a question off-topic, especially for you, my friend Maziar...

Is it true that you can install Windows to a flash drive (or thumb if it differs. For me flash drive, thumb drive, USB flash is all the same thing - USB flash drive...) and it'll last for a long time, like, 10 years? If so, why would somebody want to install it on a hard drive or even more expensive SSD? I'm talking about big sizes now - 32 or 64 GB flash drives...

I like taking risks. But still, my teacher said it is possible (for a long time), and that some people have actually installed it.
About 560m - I've been there. I always go there to look at game benchmarks, as it's not an "artificial" benchmark like 3dmark.

Agree. About 560m. But about flash drives: why are they slower? Are USB3 slower too? It should be about 3GBps, gigabytes, not gigabits, while SATA 2 works with 3 gigabits per second. Or am I wrong here? About failure rates - do you mean for a long time? What if the computer (in my case) will be on 24/7 and it'll be used for rendering?

one thing I wanted to mention, flash drives heat up during prolonged use. my manufacturing principle, they don't have any features to improve cooling as they arent meant for prolonged use.

so as maziar said, it's possible to run windows from it, but the question is how long that flashdrive will last? from a reputable manufacturer, maybe year or two, from some 3rd party, you'll be good if you get 6 months out of it via having it run 24/7.

I don't think having an OS run from flash drive is a longevity solution

It's your call,but if I were you,I'd installed it on HDD and then when the SSD prices dropped(which will be soon),I would add a SSD and install the OS on it.

I've heard that in 2012 we'll see a price drop.(I'm waiting for it as well )

You can customize AW M17x R3/M18x with 6970M.
As for GTX 470M,I couldn't find any laptop with it,but 3 Sager laptops offer 460M,485M and 6970M
NP8150

NP8170
http://www.xoticpc.com/sager-np817 [...] figure=yes
NP 7282
http://www.xoticpc.com/sager-np728 [...] figure=yes

It does ? at least xoticpc doesn't show it

It's best to go to the official web sites. Well, they actually had an option, 470+8gb, for $1800, but now they have 6970 for $1900 or more

No one knows how the next gen cards perform so if you need a laptop right now go for it.
I choose 6970M over 470M because it's much faster and also PhysX is not a big deal,not all games support it and you'll get a notably slower FPS with it enabled

so if you want physx, get an nvidia card and stop trolling...

I am looking at the MSI GT683R with the GTX 560M or the Sager NP8150-S1 with the ATI 6970M. The Has much better sound and is just cooler but the Sager has the ATI 6970.
Any Thoughts???

So, what laptop are you thinking of?

your not listening to everyones opinions at all so why ask? yes you should get the 6970 and yes it will be worth the extra money and you will NOT be able to play games will having 3ds max or maya open with a large fill open it just will not happen unless you have a SSD.

also to elaborate on why you wouldnt want to install windows on a flash drive is because they have slow read/write speeds most if im not correct have a read/write speed less then 20mb/s while my hdd in my laptop has like a 65-70 read/write.(thats a hdd).

until you start rendering things stick with 4gb then if you start to then max out that laptop. 8gb does not go far with large fills and highly reflective materials and the such.

ive never priced a usb3 flash drive but i thought i read that they were expensive and still limited to relatively cheap and slow flash memory.

and 1000 polygons is barely anything? are you sure your reporting the right number? i have a file open now with 1million polys and i have had some with up to 25mil? regardless your new comp will be able to handle about that range.

control + f and search for a 6970

Couldn't find Asus

you need to level up your googling skills
http://usa.asus.com/Notebooks/Gaming_Powerhouse/G73SW/

No one is pushing you toward anything.
It's your job to decide what you want.

You said Asus might have a laptop with 6970, I said I couldn't find it. All Asus laptops I could find are 460m/560m (I think there were 560m laptops). That's why I said you're trying to push me a laptop with 460m/560m.

I decided. It'll be either Sager NP8170 with 485 or Malibal Satori

asus g74sx i7 2630qm @ 2ghz (8 cpu) 16 gb ram nvidia gtx 560m 3gb got it for $1200
