Which graphics card should I choose?

Q. I have the choice between a GeForce GTX 680 or a Dual AMD Radeon HD 7870.
From what I've researched the gtx 680 is more powerful by itself,and the 7870 is slightly less powerful on it's own but will having two of it make up for that?

A. Well, in your case, I suggest that you should go for the AMD Radeon HD 7870 (dual). Although the NVIDIA GeForce GTX 680 is more powerful than the single AMD Radeon HD 7870 but with two of these graphics cards will surely outperform the GTX 680. I also suggest that you should get a AMD CrossFireX connection which will enable you to use both of the graphics card together and this will also lead to more power by the GPU. This sort of connection will let you view contents on upto 4-5 monitors in a stretch. So, if you are a gamer, you could use this setup to make yourself a virtual cockpit in Flight Simulator X or Train Simulator 2012 etc. So, my advise, go for the dual AMD Radeon HD 7870 and since one HD 7870 is a dual graphics card (this GPU comprises of 2 graphics card in HD 7000 series. Check the site for more info.) this means, you'll be having the power of 4 GPU's in a single computer!!!

But, if you buy 2 GeForce GTX 680s and connect them with a SLI (Scalable Link Interface, same as CrossFireX) connection, they will be more powerful than the dual AMD Radeon HD 7870 in their performance, functions etc.

In short, go for dual AMD Radeon HD 7870.

Which needs a faster computer to run:Autocad or 3ds Max?

Q. I know they're for different things, But I was just wondering which would need a better computer.


I've looked at the system requirements, But for AutoCad it doesn't say much. So I'd like to get some user opinion.


Specifically, I'm most concerned about the graphics card. So please take that into account too.


Also, I'm talking about comparing the 2012 versions of each, But if performance in the past is still relevant that's fine too.

Thanks.
Edit:Still take CPU, Etc into account as well

A. The only time you need 'fast' is rendering on 3Ds Max. The AMD64 Phenom-II x6 CPU is the most remarkable video rendering setup I have ever worked with and that is backed up by cpu comparision charts. 1 minute of playback video takes 1:05 processing time on the AMD with SATA drives running 7200 RPM wired with an ASUS motherboard. My AMD64 Athlon x1 takes 20 minutes to do the same video.

With 3Ds Max you have a choice in preferences whether you want the viewports to be OpenGL, or the AutoCADDY graphics library, or maybe they have added the Microsofty way by now. You add an nVidia card for vers. OpenGL 1 and vers. OpenGL 2. ATI Radeon is only supporting the OpenGL 2.0 version.

Even though ATI is AMD and one day the GPU/cpu chips may merge, I have always like nVidia because they support Linux so well. The colors seem brighter on ATI.

So, admit the machine you want will see heavy Gaming and that merits the costs of a high-end GPU card. The i7 does games better because software makers have optimized the Intel for their software.
