My Review of GTX 670 in OS X and Win7!

The 8 pin is for overclocking purposes. If you don't overclock, it is highly doubtful that you need it. GTX670 that has 8 pin are using the GTX680 PCB. The chip itself is fine with 2x6pin and the extra components on the PCB is unlikely to make a huge difference. Most GTX670 that come on GTX680 PCB are overclocked but not enough to increase power usage significantly. It is when you dial up all the settings in the overclock utilities (EVGA PrecisionX for example) that you will see a difference.

btw the GTX580 use a lot more power.

Got both the 570 and 670 in today, however I only installed the 570; Installation went without a hitch but had some initial difficulties in removing the stock 4870 because I wasn't aware you had to move the fan assembly out of the way first.

Starting up for the first time was a little worrisome as the screen stayed black; Forced powered down and restarted and thankfully the log-in screen came up. Card was recognized and I updated to the current drivers and firmware. Initially the card wasn't recognized in Premiere CS6 so after a quick search I found a simple guide to insert the card into the list of recognized cards for both PP and AE. Found another guide to enable OpenCL and got Luxmark to recognize the card and run a test. All in all, a pretty painless update, although when I run System Report, and select PCI cards, it comes with an error message and cannot display anything; Is this normal when using a PC graphics card?

Already got an RMA for the 670, so it'll be going back tomorrow; Just seems like the general consensus is if you want a graphics card for gaming, the 670 is a pretty damn good card, however if you're more interested in CUDA performance(and the 670 apparently is no slouch), probably will be better off with the 570.

Yeah, this is definitely the scariest part of the installation process

I just upgraded from a GTX 670 + Radeon 6870 to a GTX670 + 5870.

Again, no issues. I also have a Mac Pro 1,1 I'm going to attempt Crossfire 2x Radeon 6870 as soon as I get my next PSU .

I'm going to do a How-To retrofit a PSU into a Mac Pro externally. I've already done one... the next design will be how to do it without cutting any wires on the PSU (in case you don't want to void the warranty). There's already internal products, but it seems like they'd be a pain to actually get working inside a mac pro, plus they're slightly more expensive than an external unit (though less unsightly for sure).

make sure to post that it will be an interesting read thanks!

GTX 670 here running in Windows and OS X with no problems at all in either once booted.

Boot remains an issue; I'd assumed I'd still be able to hold option on startup and tab around in the dark to select a startup disk without the display working as the disks are always ordered the same way, but the boot selector doesn't even appear to work with the 670 in there. No matter how many times I hit tab or return nothing loads and I don't hear the hard drives seeking at all. Hmm.

Question about "helper" cards (planning on an old GT120): does the mere presence of the helper card cause the 670 DVI out to display the boot screens properly? Or does the monitor have to be plugged into the 120 as well with input switched back and forth?

No, the EFI on the GT 120 only works for that card.

Thanks for this slughead, very informative. Have you had any issues when upgrading to 10.8.2?

Price drop on gtx 670 $334.99 w/rebate

Thanks for the review--it's always good to get someone's first-hand take.

The GTX 570 is plenty good for my gaming needs, I just would prefer the cooler, less power-intensive GTX 660 TI or 670. I've just read a lot of mixed reports of the 6xx in OS X...granted most of it stems from FCPX issues (which doesn't affect me).

Still, I'm leaning towards getting a cheap, used 570 on eBay or waiting for better 660 TI support. I have no clue what the likelihood of that latter is--I'm guessing it's dependent on a GTX 6xx appearing in an iMac or Mac Pro.

Just bought myself a GTX 670 for use in my Mac Pro 5,1 hex which is supposed to be delivered tomorrow. It's the 2 GB version.

Am I correct after my reading that I will need to download and install a patch to get OpenCL working properly?

You seem confused.

Link?

Under 2049 Mb doesn't need patch in 10.7.5 or 10.8.2.

from the OP:

any more than 2GB and you have to hack the OpenCl drivers

What about the card standing directly on that amount (2049), would I need to install the patch then?

Thanks for the reply.

2 GB is 2048. I don't think you can get a RAM configuration which is 2049

Okay, the 2048. Whatever the 2GB rating actually stands for.

exactly, the point being that at 2048 (2GB) the card is fine

the issue is with cards OVER 2GB (2049 and more)

this is why I said you were confused.

Thanks for your response and help!

I got my new Mac Pro hex yesterday and installed both my ATI 5870 and Nvidia GTX 670 with no problems.

The GTX screams in games under windows. So far haven't had any lag on any games I play. Great purchase!

gtx 670 purchase - last few questions

Thanks for all the info guys, this thread is the best. I'm pretty up to date on most of the gtx 670 info, and as my 8800 gt on my 2008 macpro is dying on me it's time to upgrade. couple last questions:

what's this about the pci-e slot only working at 1x speed in MacOS AND windows?? I saw in another posting that the newest nvidia drivers fixed this on mac, I assumed it would work at 2x speed at default in windows anyway?

I'm using the card primarily for Final cut pro editing, and gaming in mac/windows. I've heard a little about issues with fcp, anything major? Should I consider the 570 instead? I'm trying to futureproof a little and like the 670 more as the price is pretty similar, but dont want any headaches. I'm going to be upgrading from snow leopard to mountain lion as it is, just want to keep everything running smooth..

finally, the cost. the gtx 670 is about $400, I saw at best buy and tekserve today some cheap options at $250 and below (gtx 560ti, radeon 5770), are those decent options? I like being able to play new games at super settings but just have a 1920x1080 monitor and I play ps3 on my big tv most of the time.. My heart is leaning towards the 670, wallet definitely not haha..

thanks for the input guys, appreciate it

Just updated, it works

Great news. I ordered one last week, should turn up in the next couple of days, so I'll se how it is compared to the 570 I'm using now.

i did it

ordered that EVGA GeForce GTX 670 FTW 2GB from newegg. Gonna update this thang to mountain lion, should I stop at 10.8.1 or are we good to go?

cant wait to get it, i'll let yall know how delicious it is

Hey guys, excuse me for a stupid question, how do I power both graphics cards? The connector from the drive bay is completely different and there are only 2 connectors on the motherboard, so the 670 uses them all.
