Dual 512MB NVIDIA® GeForce® Go 8700M GT – SLI Enabled

dose any one have any benchmarking tests on these 2 cards

i can find bench tests on 512mb ati mobile radeon hd 3870 x2 ---------witch is one graphics card and 2 chips on it
but not the one i looking for with cross fire

or dose any one know what one is better and why

thanks

HAY THANKS

WHAT ABOUT ATI 512MB ATI Mobility Radeon HD 3870 CROSSFIRE
vs
GeForce® Go 9800M GT SLI

cool but with alienware laptops if i go with the nivida i can only do core 2 duo

but with the ati one i can do quad core

so is it better to have a strong processor as well as a good card or am i wrong


two laptops are alienware M17 AND M17X

cpu matters more when it comes to resolution, if u play at 1920x1200, u benefit from gpu, and 1024 cpu just as exampes.

Personally I think games are more gpu dependant and would benefit more from a stronger gpu.

cool thanks one more question do you know if you can upgrade the gpu at a later stage i heared that the gpu are not built onto the motherboard so you could swop them later

The GPUs are in a standardized slot, usually some form of MXM (I, II, or III) but in general upgrading graphics is difficult because of lack of availability and extreme cost.

Oh sorry, i mean 2x9800MGTX not 2x9800MGTs thanks for clearing it up
9800MGT has 96 StreamProcessors which is like 8800MGTX.

guys, which one is better..


- Dual 512MB ATI® Mobility Radeon™ HD 3870 – CrossFireX Enabled or 1GB Ddr3 Nvidia GeForce 9800M GTX Graphics?


- Nvidia Quadro FX 2700M Graphics with 512MB DDR3 or 512MB ATI® Mobility Radeon HD 3870?


or which one is at the top among these four GPU?

Thanks!!

Depends on the game/apps/situations.
In general the GF9800M GTX will beat two MHD3870 in Xfire, also especially for laptops multi-GPU solutions are terribly tricky, especially since you won't be able ot download official ATi drivers, patches and fixes as often (ATi doesn't supply them directly, unlike nV) which are the lifeblood of that type of solution.

HD3870 would be better performing in general, once again with back-forth, the FX2700 is essentially a GF9700M.

The GF980M GTX is currently the best mobile graphics card available (but the high-end HD4K are coming soon [launching/previewing at CES]), and that nV is providing their mobility drivers directly from their site that's a HUGE advantage IMO over ATi if you don't want the hassle of having to mod drivers for your laptop which I hate having to do for my Vista (& W7) Partitions.

Yeah for me it's about stability and the ability to use all the features.

If it were up to either ATi or Fujitsu, I'd still be stuck with a laptop with 1080i macro-blocking and black screen issues (and my bedroom TV is a 30" 1080i CRT) and the st00pid lack of full-screen flash suppot (no full screen YouTube! ).

I can't believe that ATi still thinks people buying gaming or multimedia laptops would be happy without essentially driver updates !! At least finally nV got it after years of being equally ignorant and arrogant about it. They both used to say 'too bad, go moan at your laptop vendor', which is ridiculous I bought it for X CPU and Y graphics chip more than Z paint job and Logo!

lol ive always stayed away from laptops (expect my brothers alienware i accidently broke a year ago and blamed the cat =P...) desktop all the way
