Hi,

I am going to buy a laptop ,is Dell Inspiron any good ...

Two models are quite good for my needs Dell Inspiron 14R and Dell Inspiron 15R

what you guys think about it?

The two models differ in screen size and graphic cards ,the screen size doesn't matters much for me but the graphic card does,so I have two choices

1) NVIDIA GeForce GT730M 2GB VRAM

2) AMD Radoen HD 8730M 2GB VRAM

Both cards are almost similar,so I am confused what should I do...

Thanks

Debjit Roy

NVIDIA is preffered

Radeon used to be superior but I agree, go with NVidia.

Many games want NVIDIA

Mathematica can use Cuda to greatly speed up computation. Cuda is a NVidia card feature.

Thanks for the reply.

I think NVIDIA GeForce GT 730M score 2 points as its a bit better than AMD Radoen HD 8730M in performance and also it have drivers for linux which are better than ADM's drivers.

But I see AMD Radoen HD 8730M support full DirectX 11.1 in case of NVIDIA GeForce GT 730M it only support some features of DirectX 11.1,that's what making me thinking ,as for 3D development its better to have full DirectX 11.1,but again NVIDIA GeForce GT 730M have PhysX which is an another area I would like to explorer...

Any suggestions ....

I do not have any experience with those cards but price would also figure in. I have Radeons and they are dogs.

I am looking over here,

Sure wished they showed prices.

Well after more search I found Nvidia 730M doesn't support four non gaming DirectX 11.1 features ,two of them are for 2D which I don't need in my 3D programming and other two seems to be not very useful for my 3D work.The plus point of nvidia is I get features like Optimus, PhysX, CUDA, 3D Vision, FXAA, TXAA, OpenCL, Direct Compute,and much more which could be explored in 3D programming...

So I am going for Nvidia ,I am not concluding AMD is bad but at this very moment the over all advantages is given by Nvidia

Thanks bobbym and Agnishom

You must have found the price okay. Will you just purchase a laptop with it installed or install on your own?

I will purchase a laptop (Dell Inspiron 14R) with it installed.The over all cost seems ok.

Nvidia GeForce GT 730 M is designed for laptops/notebooks,for desktop their are other series both from AMD and Nvidia like Nvidia GTX series is best on desktop platform ,for future I am planning to buy a graphic card from GTX series for my desktop.
