GeForce GTX 660 Ti or 670?

I was wondering if the better deal would be a GTX 670 for $319 or a GTX 660Ti for $239. Anyone care to comment?

I finally got some replies and I don't like what I found out but it could be worse. It has been found out that the new GTX 600 series has gotten worse for video editing and from many tests a 570 will actually beat a 680 and 670. The only thing I don't like is that it will use 29% more energy than the 670 but the trade off should be worth it. Now, the only question is do I get the 2GB or the 1280 or 1.25GB one? Is is worth an extra 80$ to get .75 more GB???? What say you all??

Probably not. Also, I'm gonna say right now that I'm very unsure about what I'm saying, but: wouldn't it be better to get an enterprise-grade GPU? E.g. quattro.

It would, but after reading many of the tests and results about that you really have to go pretty expensive to get anything better and the price point is just not good enough to justify it. After much discussion with Vegas users and people that use Nvidia for editing it is a consensus to use the 570 or 580. I went with an EVGA 570.

Why not an AMD GPU? What is wrong with the 7870 you have?

It does not work with my software. I thought it might but it just doesn't .

Crap that sucks. Because they have better GPU compute than the nVidia 6xx.

And so does the 570.

Yeah looks like it's your best option - even with the power draw. What about picking up a second hand GTX580 ?

I drew the line with the power draw at the 570. The 580 is crazy for power.

Yeah I used to have a GTX480 - I know all about high power draw haha

The 570 draws about 31 watts less than your 480 did. Still pretty high but better than the 580 which is about 6 less than your 480 was. I would have like to use the less powered 670 but I want performance and stability and the 600 series just don't give that with video editing.
