  Thanks Stratdragon, very cool ! where did you get the specs ?  Exactly what I'm sharing.  Only 960 is Dirext X12, slightly higher OpenGL, and a few other slight increase.  Memory is very similar.  Only 670 released 3 years ago.  Oh, well I'm not complainin, just curious.  I had an honest sales rep

  nVidia provides specs for all their cards on their site. Here's the one for the 670. Just replace the model number to get others (or do a search on Google; the specs page is usually at the top of the list.

  http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-670

  Of the 960 versus 670, what's "better" really depends on the rendering engine you're using. For Iray, what matters most is video RAM and number of CUDA cores ("Unified Shaders" in the above). In Iray-land, the number of cores is the largest determining factor for render speed. Other aspecs like RAM speed are important, too, but rtender times are best benefited by more cores.

  The 670 is actually a nice board for budget Iray rendering. It has a few hundred more CUDA cores than a 960, and because it's an older card, can be found used on eBay for $100 or so. Be sure to get a version with at least 2GB; the 4GB version is a little more. (Remember that nVidaa specs are for their reference designs. They license their boards to other manufacturers, who have the option to put less or more VRAM into them.)

  Thanks for reply Tobor.  I like the side by side comparison Stratdragon uploaded.  Thanks for the info, what I needed to know.  Now, I know what to look for in a future card.  I already have the 670, which is a major improvement over 630.  Plan on picking up another one for SLI.  My 630 only had 96 cuda cores.  Yikes !!!  I rendered a scene 630 card only, took 5- 6 minutes to reach 1%, with 670 card alone took 4 minutes something to render complete scene.  670 with 8 core cpu render took approx 2 minutes.     

  Yeah, I told the sales rep exactly what card was used for, 3D rendering on a budget, I had a GTX 630.  Thought he was just trying to dump off an older card on me, when he recommeded 670.

  But on GTX 960 with 4GB GDDR5 video RAM, larger IRAY scenes can fit in it.

  There are also GTX 970 with 4GB GDDR5 video RAM, which are getting cheaper, as well.

  As I said above, it depends on the manufacturer of the card. There are cheaper 960s with only 2GB, the same as there are more expensive 670s with 4GB. Most nVidia models don't have a specified amount VRAM, and they are often available in several different "flavors." 

  @awesomefb, If you do get the 670, I'd consider going a little higher and opt for the 4GB model, especially if you won't be keeping the 630 as your display card. Look around for a good price. Most will be either used or refurbished. EVGA's version is superclocked, comes with 4GB, and is DDR5.

  The GTX 960 is not very good for the 900 series. Take the GTX 980, it is about twice as fast as the GTX 960 (and the GTX 670). The GTX 670 should cost much more than the GTX 960. That the GTX 670 is cheaper is just plain false.

  Here's the 980 up against the 670.

  Thanks to all replies, learned a thing or two about video cards. 

  @Tobor - I already have a 670 video card.  Couldn't find a 4GB.  Your statement is very true, I've alway's been a fan of Evga, I've never had any issues with thier cards past decade. 

  @AlienRenders - I purchased a 670, for less then price of 960 & 980 cards.  Reason I was asking, why? price on newer model cards were alot higher then older cards, and yet older cards havd similar specs, some older cards perform better then newer ones.
