lolz... its in no way comparable to a gtx 470 or 6790 or any other high end gfx card for that matter...
it will run games like mw3 at 30-40fps max settings x4aa @1080p, while the 460 will max it easily at 60+ and the 470 will do the maximum 91. so who ever told you it was as powerfull as a full size desktop card was yankin yer chain...
dont get me wrong its a nifty little card and does well for its size but its nowhere near as powerful as your trying to make out...
1 think i did laugh at on the benchmark vids on youtube was the guys would say oh max settings 30+ fps but wouldnt show em on games like crysis 2 and dirt 3 but would for much weaker titles like mw3...
the truth is like many other things bent to suite its purpose.
its comaparable to the 6770 in performance which is definitely low mid for a desktop but pretty high end for a lappy.
its about 100 shaders short of a gtx 460 desktop card which puts it just above the thr gtx 270 and just belowthe gtx285 so will be about 15% slower than a gtx 460 which in turn is more than 25% slower than a gtx 470 can you see where im going yet?...
oh and the 660m 670m, 675m and 680m are not kepler cards there original cuda based. not fermi or kepler going by nvidias own site. kepler cards are specifically branded as such although hexus forum claims the 660m and 680m are kepler while the 670 and 675 are fermi (but they forget to tell your there just rebadged previous gen cards)... personally i would rather go of what nvidia have them listed as and thats cuda.
also kepler cards are dx11 not dx11.1 amd are the only 1s doing dx11.1 cards.
end result is your looking at medium settings @1080p on the 660/670 and 675 on bf3 with 35-45fps on a multiplayer map like gulf of oman. a lot higher with the 680m which i believe is the only kepler out of all of em performance wise.
sorry if that burst your bubble... Actually your not bursting my bubble those cards I mentioned are all mobile versions not desktop im sorry I forgot to put an m behind each gpu# but I figured a smart condescending desktop guy like yourself would figure It out? So yes they r comparable I just ordered my "crappy lappy"" last week clevo p170em with 17.3 led matte finish screen,12GB of ddr3 ram, 750GB @7200 rpm hd, illuminated led keyboard, 4x max Blu-Ray reader 8x max dvd optical drive, and last but not least amd radeon HD 7970 wich is comparable to a nvidia gtx 460 and 570 desktop card. It will run crysis 2 in ultra details, 1080p @52 fps , bf3, ultra settings, 1080p, @34.9 fps batman arkham city @ 100+ fps the only game it cannot run so far in ultra max settings is metro 2033 but most lappys can't (metro 2033 on my clevo p170em, 1080p, very high settings @78.9 fps with physX on. So as you can see my "crappy lappy" is quite comparable to some decent gaming rigs not highend but plenty capable peace love and bacon grease my friend.
the absolute worst thing about this card is there selling it as high end when it just isnt... they have re-badged and re-badged there cards so no1 actually knows what the hell there buying... not only that there charging the moon for em 2...
the 6770 costs what $150 bux but a 660m cost nearer to 300... its ridiculous.
