Nvidia 680m or radeon 7970 for £500 less?

Its been pretty much said in the title, im getting a new laptop from overclockers uk and they have two laptops that are great, only difference between them is that one has a 4gb Nvidia 680m
and the other has a readeon 7970 2gb (both are RRD5) but the one with the readeon is £470 less, is it worth another £470 for the Nvidia 680? (I have enough to get ether one)

The specs for both laptops apart from the graphics card are..

2.7g i7 quadcore proccesor, 1920x1080 screen, crucial v4 256gb ssd, 16 gig of ram.

Feedback as soon as possible would be appreciated :)

Don't really care about the price, but would rather not pay £500 more for like 5 more frames per second.

Lol

Well remember even if you use your GPU 100% 24/7 it should be covered by your warranty for a few years as long as you don't overclock so it should not break and if it does you can get it fixed under warranty.

Also the 7970m draws 75watts at full load according to wikipedia. Find a utility bill, measured in $ (or pence) per KW/H and do the math about profitability yourself.

the laptop im getting says 3 years warrenty, 1 year parts, 2 year labor, what does that mean? (thats its split into two categorys)

It says 2 year and for clarification ask them?

My dad thinks it means that in the first year anything breaks then its free repair and in the second year if anything breaks you have to pay for the new parts but the labor costs are free

That's probably right.

Running it for months or years at a time could end up wearing out the GPU or more likely the cooling fans (they have moving parts, the GPU does not) or breaking some other part of the laptop (not the gpu) due to heat. What I read was that too much heat for too long could damage some laptop batteries. Also running the fans like that will wear them out faster. However the fans *should* break before the GPU does. Once the fans are dead though nothing can run, will break if it doesn't shut itself down for safety and needs to have new fans installed for cooling before you can use it again assuming that the software drivers have managed to shut everything down for safety and keep it shut off so nothing has broken.

For example the HD 7970m does about 2175 GFLOPS compute power and my HD 6950 does about 2250~ GFLOPS compute power. The big difference though is that my desktop HD 6950 has a 200watt TDP and your laptop HD7970m has only 75watt TDP so yours probably draws a whole lot less power to do nearly the same job. TDP is not the same as power draw but I'm guessing it is at very least related. The benefit of the desktop card though is that I can overclock it more (better cooling and more power) and it's cheaper (I think) cause they can make it bigger.

Yes, like Crysis 3, Tomb Raider, Hitman Absolution and so on...

Interesting development has happend!!!! I MAY have found a laptop the same, but an Nvidia 680m is £200 more, not £500 more, so is it worth £200 to get an Nvidia680m rather than amd radeon 7970m? Or is radeon in fact better, because half the opinion is that with its updated drivers, radeon has become better? Would appreceate fast comment :D

Here is a link to the laptop in question http://www.pcspecialist.co.uk/notebooks/vortexIII-17/
WOW, uh rove i found something... i found where overclockers get the laptops they modify and well... WOW,,, Do you think its worth paying £200 more to get 7970m CROSSFIRE!!! 2x cards :D

Or hell, is it worht it to go all out for the laptop at £2000 with an Nvidia 680m Sli?

VERY IMPORTANT - For price sake, would it make a big differnce if i lowerd the CPU fro 2.7ghz to 2.4ghz?

big differnce to performence i mean

Whoops, i forgot to post a link to the laptop xD http://www.pcspecialist.co.uk/notebooks/vortexIII-Elite/

Ok, i have found a better site so when i choose laptop, if its not duel GPU one the it will be Nvidia680m laptop for £1600

casue apparently people are saying duel GPU can been kinda... tricky

Ok, so now my plans have changed basicly, im getting a laptop with an Nvidia 680m for £1550, should i pay £600 more to have it upgraded to Sli (2 cards) or would that jsut be overkill xD and would it hurt the performence at all to lower the 16gb to 8gb ram and the cpu from 2.7ghz to 2.4ghz for the sake of price

lol, the topic has changed that much i really should change the title xD
