I've heard the difference between the 660ti and the 670 is negligible with rendering for the most part. It seems quite unanimous. The real question is whether the entire 600 line from nVidia provides any boost above the 500 line. Research indicates that if there is any improvement, it is unfortunately negligible, e.g. 670 over the 570. Supposedly the Kepler architecture of the GTX 600 series results in "crippling" of the computing power but provides greater power for gaming applications at this low price and also at low voltage. Not sure what it all means but it's from information gathered as of now - and I don't know that the 600 series works reliably with Vegas either.
I don't care anything about gaming. Only about our the world of editing. So is the 570 going to give a better rendering environment than the 660Ti or 670? I guess that is what I am looking for but I don't think many really know for sure, right?
Read above - the difference between the two is probably negligible. The real problem is, as I've said, that my research indicates that nVidia has made the 600 series a gaming card. Supposedly - per rumor - nvidia wasn't happy that people found their prosumer video cards excellent for rendering and didn't feel a need to buy their high end cards. Hence the new architecture supposedly runs no faster than the 500 series and sometimes even slower. This is all second hand information but it has been often repeated by people who seem to know what they are talking about.
MORE importantly, look at Sony Vegas' benchmarks. They use the GTX 570 and I know that card works. Look in the forum - so many people saying that the 600 series cards are not even recognized by Sony Vegas 12 to use for GPU acceleration. The only time I've seen anyone say the card is even recognized mid-November on the latest build of Vegas 12. No one knows how buggy the 600 cards are right now or whether these cards will work properly within the next year. Sony won't speak to you for technical support unless you pay them and sales says "supported means we'll get around to fixing things."
IF you want to see the video on your screen, yes, it will probably work. But if you bought it for video encoding, it might not work at all. Still can't find anyone who has used Vegas 12 with the 660 ti. Believe me, I'm not happy. I have a 660 ti card en route which will almost certainly be returned finding out all these shenanigans.
So, I have changed my mind TheLaw like I said in the other post and am going to meet halfway. I will go with the 570 which is a little slower than the 580 but saves about 40 watts of power usage. The 570 is proven but I wonder if 1280MB of 1.25 GB is enough? Or should I look for the 2GB 570? There are not a lot of these around but they are there. Anyone care to steer me to a good deal? I think I may have found one but someone may know of a better one. Thanks.
It's an insanely great price, at least I think so. At least you know the card works with everything and I'd just suggest you making sure you have a powerful enough Power Supply Unit and you should be good to go. I'm almost definitely going the same route as I don't do gaming.
Regarding compute performance... take a look at this:
When you have got the card up and running could you please run a few tests i.e. rendering a minute or 2 of the timeline and with/without GPU assist on for preview and your rendering Codec(s) (if they have their own GPU setting)
It is very interesting how much such a card improves (or decreases) rendering speed on a machine with that big Ivy Bridge CPU.
