Here are just my thoughts on these two very different setup. This all came from my experiences and I am no expert. This is just informative for people who may or may not be choosing to buy video cards.

There are a lot of hype and anger between both sides. I originally had a gtx 670 FTW SLI setup and i LOVED it. I bought them for $400 each (before tax). installation, evga precision x, and nvidia drivers were all amazing. I would have to say the temps on this setup were amazing. People are 100% correct to say that this fan style is better for SLI. I rarely went over 60c when i'm gaming, and I don't think I ever saw numbers go higher than 68c when I am benchmarking or stress testing.

Here is my Unigine 3.0 score with clocks at 1200+/1750.



As you can tell they are not too shabby. it was actually a very good setup. However I did notice stuttering and some performance drops when I gamed at 2560x1440. I believe it was because of the vram limitation at the time. Skyrim, Hitman Absolution, and Battlefield were a few that got affected.

At the time I decided to downgrade because I needed money and bought myself an MSI 7950.Now that I am working again, I bought a 2nd one just for kicks and started messing around with it. I paid $300 for them (before tax). They are NOT kidding when they said drivers were a nightmare. For 2 days I couldn't figure out why my computer wouldn't recognize the video cards. Everytime i tried to install the drivers it just said "device not found". I for sure cleaned up all my drivers from nvidia and it wasn't until i found THIS THREAD: http://www.overclock.net/t/988215/how-to-properly-uninstall-ati-amd-software-drivers-for-graphics-cards that the drivers finally installed (which didn't make sense cause I was trying TO install the amd drivers...lol). It was a mess. But after the drivers were installed I don't think I have come across any problems yet. The temps are a little higher as expected (because of how the coolers are) but its not as bad as I was lead to believe.

Anyway, I did a mild OC and got it to 1100/1350. Here is the Unigine 3.0 score for that:



I'm no expert, and i don't know what clocks of AMD translates to Nvidia, but all I know is I didn't really push either that hard and I got these scores. It was impressive to me that it scored this well. I have been playing games as well and it has been pretty consistent. Don't ask me to compare these cards in 1080p. I wouldn't know. But so far, for 1440p, price vs performance its definitely the 7950. I'm actually glad that I ended up switching... although I hope I don't ever run into more driver problems.

If you guys have any questions or concerns, Or need to me try/check something let me know.

p.s. I lost my screenshot of the stock gtx 670 SLI unigine run

damn that would've been a good comparison.

^^ Don't believe the propaganda, there is no noticeable difference.

You guys and drivers...

I swap between cards several times daily, and never ever have an issue with installation.

Heck most times I just shut down without even uninstalling drivers and toss in either an NV or AMD card.
I even ran quadfire today without needing a driver reinstall.

But anyway, good choice.
I'll take CFX over SLI everyday of the week, except with FC3, SLI owns.
Prepare yourself for the stuttering mess if you play FC3.

Probably user error that you couldnt detect your cards. I have change several times my 7970's between a sb-e and ivy rig and never had this problem. Sometimes windows mess up with the drivers.

Not that I have noticed. I would have to say they both have the same smooth feeling. Both setups do have weirdness here and there, but so far I have gamed for a few hours with the 7950 CF on BF3 and if I didn't know I switched video cards, I wouldn't have known.

So far games I have tried that I gamed heavily on the 670 FTW SLI:

Guild Wars 2
Battlefield 3
Far Cry 3 - stutters a little for me, but not too much... but maybe I haven't gotten very far in the game... so i might come back to this.

It actually is pretty smooth gaming experience so far.

I have yet to try the CFX on:

Witcher 2
Skyrim
Borderlands 2
Batman: Arkham Asylum/City
Dark Souls
Sleeping Dogs
Walking Dead
Alan Wake

When i get around to it, I can make more comparisons.

Yeah I wouldn't know what to tell you why it happened.

You're probably right.
