So CF HD7950s overclocked they will be over 100% faster compared to a GTX 680.
I prefer the affordable cheaper and better GPU compared to a better GPU at 3DVision support.
I will do this as well when next generation of cards come and AMD take the edge again, I will buy an AMD GPU if it is more powerful sacrificing my monitors 3DVision support.
Don't get me wrong 3DVision is awesome but still doesn't worth buying an overpriced card just for the sake of it.

Yes it is worth paying more for 7% less performance approximately if you want 'real' 3D Vision because AMD doesn't do 3D well at all gaming.

I see, I just asked cause when I upgrade I usually like to get the best single GPU card and will probably Crossfire or SLI in the future. I'm guessing getting a Gigabyte 7970 and overclocking will completely best the GTX 680.

the problem is quite a few cards are voltage locked. so pick one which allows voltage control or has a high stock voltage (HD 7970 Ghz and HD 7950 boost) are things to consider. the Gigabyte HD 7970 Ghz comes clocked at 1.1 Ghz out of the box. price 450 bucks.

With that being said, does a 7950 CF setup allow for 3d capability?
Which is the better option for fps?

Obviously two 7950's will be huge performance over one 680 but it's not ENTIRELY just about performance when looking into 3D Vision. Ask yourself if your entertaining the idea of 3D Vision as a main staple of your system or just a side fun supplement.

If your going down the 3D Vision road seriously for gaming you want to look at what 3D offers from both AMD HD3D and Nvidia 3D Vision. In short they each support their own monitors and choosing which monitor will also decide which GPU to choose because they are married to each other for 3D Vision support.

Example is the ASUS VG287H with Nvidia Vision & Samsung SA950 with AMD HD3D. Depending on which monitor you choose will decide which graphics card you'll need or vice versa. So once you've decided you'll need to make sure you pick the right monitor.

Here is the most recent review of 3D Vision by Hardware Heaven that really gives a good idea what 3D gaming is like between both AMD and Nvidia versions.

Hardware Heaven - NVIDIA 3D Vision 2 featuring the ASUS VG278H Screen where they are reviewing the monitor but comparing it to AMD HD3D.

NVIDIA 3D Vision 2 featuring the ASUS VG278H Screen
Quote:
The HD3D hardware, other than the graphics cards, is very much a mix of quality (with some screens and glasses being truly awful) and the drivers, developed by independent developers, do not offer the same level of quality as AMD's own or NVIDIA's. Then when we do play the experience rarely is without issue and often very much frustrates.

NVIDIA will continue to dominate in this area... and dominate they do. At every step of the 3D Vision 2 experience it is clear the user and ease of use is a key priority. That begins with a wizard which helps us set the technology up and continues in-game where we get any appropriate hints to help us maximise the quality of 3D.

Nvidia has housed 3D Vision support on a hardware level and has remained vigilant on keeping up with games and consistently improving games supporting 3D Vision with every driver release. AMD relies on third party softrware for their 3D Vision gaming. Unlike PhysX, 3D Vision is not dying or going away, as more 120 Hz monitors hit shelves at more affordable pricing, we might see an even bigger increase of 3D Vision with newcomers.


Samsung SA950 27in 3D monitor review

Quote:
This is a shame because Samsung's chosen methods of displaying 3D - TriDef software and monitor-side processing - aren't as immerse in the games we tested with.

If your going the HD3D route then you'll want to look at the Samsung monitors like the Samsung SA950 27 for what I found to be the best monitor for HD3D when doing my homework going into 3D Vision myself. It is one of the best monitors despite it's reviews for HD3D. Aside from 3D Vision though this monitor is a GREAT monitor anyway. It's a glossy panel which may or may not be a drawback to some.


As for 3D Vision Blu-ray movies Nvidia or AMD HD3D not as big of a difference honestly. Nvidia 3D Vision 2 monitors though really improved 3D vision visually as it's not dark at all any longer. Quite impressive.


Lastly, keep in mind when you switch from 2D vision to 3D Vision gaming FPS gets cut about 45%. Optimal peak performance 3D Vision is being able to obtain 60 FPS and minimal 30 FPS. SO if your card is sporting 100 FPS in Battlefield 3 campaign when you turn on 3D Vision it drops to about 50-55 FPS.

Hope I've given you some food for thought if your seriously thinking 3D Vision. After one year myself, I find I still like to run through a game after I've played it once in 2D and do it again in 3D Vision just for fun. Not as much as I did at first I'll admit but it's still there and it's entertaining.

This is the problem i see the 680 is still on hell of a card that will run any modern game at good lvl's of fps and do 3d very well at the same time....

Amd are good cards also but to say one isn't worth buying is just lame..........

There is nothing wrong in buying a 680
post #46 of 138
There isn't anything wrong with buying either. Just as Arizonian said it depends on what your MAIN gaming purpose is going to be.

3d: Nvidia is just the best so far for 3d.

2d mostly with a bit of 3d for fun you can go for either.

but just 2d for now the ATI cards are really hard to beat for price performance.
Small wonder.

No. People need to stop with the ''79xx are god'' mentality. As a matter of fact, the 680 vs 7970 battle is probably one of the closest that AMD and Nvidia ever had.
Nvidia release new drivers, take the crown, AMD release new drivers, take it back, AMD start to lock the voltage on certain cards, give it away...

But AMD is cheaper. That's what's make it so interesting. It's cheaper mostly because Nvidia card have more features, are quieter and are more efficient.


Now, it's important to know that the 7970, the 7950, the 680 and the 670 are all in the same league. Clock for clock, the flagships are about 5% faster than their retarded counterpart, which mean that the fastest card, out of the four, will be the one that will overclock the most.


With that in mind, it's safe to say that you will have a lot more of horsepower with the 7950s in CF than with a single 680. It will consume more than twice the wattage and generate a lot of heat (they are closer than the 480s than most will adrmit), but it will be really, really fast.

no. these cards are not in the same league. nobody is going to take your word for it.

http://www.techspot.com/review/603-best-graphics-cards/page12.html

this review uses the latest drivers for both camps.

"Breaking down performance figures at 1920x1200, the GeForce GTX 680 was just ~1% faster than the Radeon HD 7970, while it trailed the 7970 GHz Edition by a 7% margin. This doesn’t change at 2560x1600, where the GeForce GTX 680 is 2% slower than the Radeon HD 7970 and 11% slower than the 7970 GHz Edition, making the 7970 the obvious choice."

Even at 1080p an average 7% lead is significant and an average 11% lead at 2560 x 1600 is no joke. In games like BF3 at 1080p the gap is 12% at 1080p and 13% at 1600p. The HD 7900 cards scale better with overclocking. HD 7950 is 3 - 5% slower than HD 7970 at same clocks. HD 7950 (1.05 Ghz) will actually be faster than GTX 680 (which boost upto 1.1 Ghz or higher depending on the particular chip) . Even a 1.35 Ghz GTX 680 will find it hard to match a HD 7970(1.2 Ghz). Once HD 7900 cards get to 1250+ Mhz they are unbeatable.

As for the OP if he wants the best 3D experience Nvidia has the edge.
