I cant decide witch one is better there is a price diffrence. Also idk if i should wait till the next "holiday type sale"
I'd go 660ti because I've had problems with my 7870 but never with the 660ti. Might be different for you though. The 660 is a solid GPU.
What are you currently using? Might be worth waiting for the next gen cards, they could be as earlier as 2 months away.

Pretty much the same, get the cheaper one I would say.
the 7870 is about the same, but the 660Ti is typically more and if you can get a 7950 for the same price get one
Why go with 7870 when you can get a 7950 for the same price as a 660Ti?
The 7950 will spank the 660Ti at stock and is supa dupa overcockable too!
I'm trying to make a similar decision... Does anybody know if Photoshop is CUDA intensive? It's pretty much the only Adobe CS program I use- I do no film rendering at all. If it happens that PS doesn't do much with nVidia's CUDA cores, I might as well hop over to AMD.
What CS? I dont even think CS5 supports native CUDA-accelerated functions? (sure someone will hit me with a stick and put you on the right track if im wrong there!)
ETA:
and just found this on CS6
" The Mercury Graphics Engine (MGE) represents features that use video card processor, or GPU, acceleration. In Photoshop CS6, this new engine delivers near-instant results when editing with key tools such as Liquify, Warp, Lighting Effects, and the Oil Paint filter. The new MGE delivers unprecedented responsiveness for a fluid feel as you work. MGE is new to Photoshop CS6 and uses both the OpenGL and OpenCL frameworks. It does not use the proprietary CUDA framework from nVidia."
Id think about jumping to AMD in your case.
Almost all Adobe products support CUDA acceleration. This does include CS5, and CS6.
Thanks for the help :)
I did some more research and it definitely looks like CUDA plays little to no role in Photoshop outside of select plus-ins. Photoshop has moved over to OpenCL for rendering, and it appears that AMD has the edge in that department.
Now I'll definitely have to consider the 7950/7970...
Beyond OpenGL, NVIDIA®—one of the leading video card and chip manufacturers—has developed
a parallel computing platform and programming model called “CUDA” (tinyurl.com/AdobePWP-03)
that runs on their own GPUs. Adobe Premiere Pro and After Effects make specific use of CUDA and
its related technologies (such as NVIDIA’s OptiX™ Ray Tracing Engine) to wring more performance
out of specific GPUs. Therefore, when we mention that a function requires CUDA, this performance
acceleration is only available using Adobe-qualified NVIDIA CUDA-enabled video cards and display
systems (listed later in this document).
New on the scene is OpenCL (Open Computing Language), which theoretically gives any
application access to the graphics processing unit for non-graphical computing. However, at the
time of this writing (early 2012), OpenCL is a relatively new standard, and currently only Adobe
Premiere Pro CS6 and Photoshop CS6 can take advantage of it under very specific circumstances
discussed later
Still uses cuda, just has OpenCL so AMD cards are not that terrible, Nvidia still work better though.
Nvidia always seems to have the upper hand when it comes to driver support. It really depends on what you're doing with your card. I have a 660ti and couldn't be happier with it but I've also heard great things about the 7870. Both are great cards and I'm sure you wont be dissapointed with either.
The 660 TI is the better performer.
not in the past 3 or so months
since the 12.11 drivers for 7000 series cards, the 7870 has had a clear lead
o.O
Are you sure about that? Last time I checked, the 7950 and GTX 660 TI were trading blows and the 7870 was inferior.

7950 is on par with the 670, while 7870 is about equal to the 660ti
Huh, I guess the new drivers are just doing really well then, because when the 7870 first came out it was slightly worse than a GTX 580, and the GTX 660 TI was about 10 percent better than a GTX 580.
Yeah those drivers are pretty crazy. Like 5-10fps across the board, like 10-20% increase on performance. Its pretty nuts really.
