Upgrade alienware m18x

Hi guys , i'm the new in here , i've got alienware m18x and i've to upgrade it to gtx680m sli a few month ago , now i wanna upgrade it to gtx880m sli . Do gtx880m sli are stable on m18x ?? (Somebody told me that gtx880m not stable on m18x ). And where can i buy the brand new gtx880m ?? ( i'm from Việt Nam where do not have any service for alienware , so sad ( )

Very need your advise guys , thanks you guys first

 

Don't get 880m's friend. Your better off with your 680m's. 780m's are a better option, especially in Vietnam where is hot.

 

880m is too hot ??? Because i wanna some big different from gpu clock ( just wanna best setting in watch_dogs ^^ ) so that i chose 880m not 780m , but why i cant take that ?? And where i can buy the brand new gpu for my laptop ^^

 

better stick with your 680m SLI, or 780m SLI if ya can afford one, 880m has some kind of stable problems despite the fact that they are 780m's clone

 

880Ms are hindered by some weird power design. Once overclocked they heat up like crazy.

 

Ok , thanks guys , i'll thinking about going up to twin 780m's . Thanks 4 ur advise . Ah 1 more question , are duo 780m's can handle watch_dogs with hight setting ??

 

Here's a video I did with 780m SLI along time ago. It was before SLI was officially supported. Those are max settings.

 

like a breeze, last year i've completed that game with a m18xr1 (2760qm + 780m SLI), max setting with 60 framerate almost the time, but you should use TheWorse Mod for best experience (lol with the name!)

 

OMG , so that these 780m's can handle watch dogs easily =))) , SWEEEEEETTTTT , thanks u guys so much

 

gtx 680 sli could handle watch dogs with no problems as well

 

I dont know #panamaniacs but my system cant handle that with the hight set , i just playing that game with low everything and fps sometime drop from 50~~>55 to 30~~> 40 >.< ( poor me ) . My system when i've played were : win7 ultimate , 16gb ram corsair , ssd 240gb , and of course twin gtx 680m's

 

i dont mind playing at 30fps, i guess is a matter of preferences

 

) maybe u right , i dont like any lag in my game , for full enjoyment

 

i think with gtx 780m sli you will experience the same behavior but the min fps will be higher .

 

Watchdogs uses up around 3500MB VRAM on the highest settings, so it should help immensely if going to 780m's.

 

Base on the video from TBone that with 2 gtx780m we can play watch dogs like a boss with the heighest setting ^^

 

You should get better performance with the official SLI support now too... So long as Ubisoft haven't broken it again
