Best GPU For Architecture/CAD Based Programs?

post #1 of 34
Thread Starter 
Hey all, I am building a new Rig and I decided to either get the Geforce 680 GTX or the Radeon HD 7970. I game a lot, watch HD videos, and do a lot of architectural design and rendering. I am only building one machine and I feel like these GPUs will serve me nicely.

I am a bit confused on which to get because I have been hearing that the 680's Kepler Architecture is not great for these programs (I am using AutoCAD, Rhino, 3ds Max, Sketchup, Photoshop, illustrator, Indesign, ect.), While the 7970 does much better. However I thought because the 680 has so much CUDA cores, it would rise to the occasion.

One of these will be my Choices most likely:

680 GTX: (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121705)
Radeon HD 7970: (http://www.newegg.com/Product/Product.aspx?Item=N82E16814121560)

At this moment I am leaning towards the 7970 from what I've heard, but still very confused. I Should also Note that I am planning on using SLI or CrossfireX IF these rendering/3d Modelling programs can benefit from it. Can someone clarify the situation for me? Much Appreciated!

7970 definately.

7970 is more of a workstation card

while 680 is more game driven in my experience.

Thanks for the quick reply Kyismaster! Does the 4gb on the 680 make any difference? If i do set up CrossfireX for two 7970's, will that be adequate? bc im aware that vram is important in terms of rendering.

I want to say no, but depends on the work.

Generally you'd use vram for gaming purposes,

I haven't been to animation design school in about half a year, so i kinda forget.

the 7970 has 3GB or 6GB, depending on the model you get, so it doesn't make much of a difference anyways.

However, I suggest you checking to see if you have enough computer Ram,

I used to render with a 8GB kit, and often ran out of ram.

If possible , I suggest having at least 32gb of ram for commercial rendering, 16gb for personal rendering.

"CrossfireX for two 7970's"

Thats more than plenty.

7970 is the fastest single card out there (( besides 7990 and 690 ))

Lol Thank Kyismaster, I just wanted a dependable set up for my freelance work and eventually when I get back into school. As I know many of the computer labs will always be crowded when people need to do their renderings during finals week and what not. I just want to have a system that will render and run my 3d modelling programs quickly and nicely. Plus make my games look pretty biggrin.gif.

I feel like anything will be an upgrade from my Core 2 Duo w/ 9500GT lol

Arrrrg

you may have a slight bottle neck with both 680 and 7970 then.

probably only 20%, nothing too severe if I remember the graph correctly.

even with a handicap, the 7970 will eat the 9500GT for breakfast.

Tbh I can deal with a 80% output, I feel like it works better than Buying a Tesla C2075 or something like that. Hopefully I can engage the CrossfireX with my programs... It would make up a bit for the bottlenecking.

I think you'll be happy with it.

Tesla... is a bit overkill, don't get me wrong, it renders like a speed demon, but overkill lol.

let me know if you get the 7970, I have a special set of drivers that will help it in openCL applications.
