He guys :hello:  , am building my first rig, and just can't decide between these two cards, and hoped that your insight would help.

First off, im most like (99%) only going to use one 24' monitor with one of the cards.
I'm probably going to have the card for 2-3 years.

So originally i was going to go with the Sapphire HD7950 OC with the dual fans, because I thinks its a powerful card, remains cool, and has 3GB Vram.

Then i held off on the build until the new Kepler cards came out, and the only other one im interested in, is the GTX 670. However two things are holding me off from buying this card
1. Heat (but can be fixed by getting non-reference I guess - but temps higher than the Sapphire 7950 OC is what im trying to say)
2. Its 2GB Vram. Considering that im going to have the build for about 2-3 years, the Vram worries me that it wouldn't be enough. However since I'm thinking that I will only use one 24' monitor, it should be sufficient. Also I have read that the extra Vram as of right now (like 3GB compared to 2GB) doesn't make that big of a difference.

One last point is that the Sapphire 7950 OC in Australia where I am situated is $480
while the GTX 670 ranges from $500 - $540, so at minimum is $40 more expensive for the better non-reference versions. Also lack of availability for the GTX 670, while 7950 is available.

So what do you think, in my circumstances would be better.
To rap up:
2-3 years longevity, single 24' screen usage most likely, $40 price difference with 670 more expensive (and less availability), Vram into consideration, and heat.

Thank you

well let me show you a bench mark of the GTX 670 vs the 7950 and then you will be able to make up your mind. It looks like at first the 7950 is out doing the 670 but that changes.

The over all showing is the 670 is better than the 7950 and all this is based on normal reference card of 2 or 3 gb of Vram. Anyway I hope this has help a little. Heat can be fought will after marked coolers or case fans. Good luck

Here's a bench on heat for the Gigabyte GTX 670 ...

http://www.pureoverclock.com/review.php?id=1506&page=17

It comes in a bit below the 7950 at load.

To me, the GTX 670 is the better card and if you can get your hands on the Gigabyte version I'd say it would be worth the extra cost.

GTX 670 is better than HD 7970 itself at stock speeds not the HD 7950.
2 GB wouldn't be a bottleneck even @ 5760x resolutions, that's what benches shown and since you're gaming @ 1080P you really don't need higher than that.

Your real problem would lie on finding a non ref model, only the Gigabyte GTX 670 was the only ref model card around and it's non stock now.

Thanks for the replies so far guys. I know that currently the GTX 670 is better than the 7950, but the only thing pushing me towards the 7950 was the extra 1 GB Vram (3GB card). However its appears from your experiences and knowledge that 2GB would be enough on a single monitor for 2-3 years to come.

Really, is that the reference 7950 or the Sapphire OC one (with the dual fans).
Yeah the Gigabyte Windforce is the only good version available here, from the store im getting it. link: http://www.pccasegear.com/index.php?main_page=index&cPa... Thats the same as the one in the review, right?

Also prices of 7950 same store offers: http://www.pccasegear.com/index.php?main_page=index&cPa...

Seems to do well with the heat.

However you guys think it will last 2-3 years with the 2 GB Vram it has?

So, you've settled to go with the GTX 670?
yes it will, from the review of GTX 680 4 GB;
Quote:
The 4GB -- Realistically there was not one game that we tested that could benefit from the two extra GB's of graphics memory. Even at 2560x1600 (which is a massive 4 Mpixels resolution) there was just no measurable difference.

Now the setup could benefit from triple monitor setups at 5760x1080 (which is a 6 Mpixels resolution), but even there I doubt if 4 GB is really something you'd need to spend money on

The 7950 used in that temperature benchmark is very likely a reference card, not a card with any custom cooling like the Sapphire. Still, it shows that the Gigabyte GTX 670 stays very cool.

Also, the Gigabyte card in your link is the same one from the review. Here is the direct link from that site: http://www.pccasegear.com/index.php?main_page=product_i...

$519 for the Gigabyte 670, $479 for the Sapphire 7950.

Honestly, for $40 more, the GTX 670 will net you better performance per dollar, with very good heat management. It's the better choice in my opinion, even with having 1GB less of Vram, which really should continue to be a non-issue in most gaming situations for a good while to come.

Yes it will go for at least 2 to 3 years or more.

I would go with the 670 also, the Gigabyte Windforce one has been getting excellent reviews and they do overclock well.
The 2Gb vram is a non issue, based on the reviews the Nvidia 670 and 680 2GB cards perform better in some games than the 3GB on the 7950/7970 even at high resolutions.
I see you are from OZ , hey mate another aussie here , I use pc case gear a lot, great online store.

Thanks for all the help so far guys, i appreciate it.

You have all convinced me that the 670 a better card than the 7950, and my biggest concern of Vram, most (actually all) of you said it would not be a problem for 2-3 years to come which is great to hear, since I'll probably have the card for that period of time.

However and i know you have probably heard this many times, aren't games like Skyrim and BF3 already using up to 2GB of Vram?

What if i was to factor in the Sapphire 7970 OC at $540, $20 more than the 670 Windforce, which would you go with then?

Finally in your experience is it better to get a card with lower Vram (eg 2GB) and then in 2-3 years upgrade to a new card, or get a 3GB and then SLI or Xfire it 2-3 years down the line?

It will not hurt to have all the Vram now because everything is heading that way and why do you think all the new cards are coming out with the extra Vram? BF3 is only using 1.5 Vram.

I didn't know about Skyrim. I am seeing a lot of problems about the 7970 cards on here at least 3 or 4 a day. But when you put the OC into it of course it is going to out do the 670.

So what ever card you buy the 3 GB of Vram is the way to go for the fucture. But the link here shows stock cards but you add OC to the 7970 well it is a lot faster. But it is up to you.

Either way you go will offer a good running graphics card the will be able to handle everything you through at it.

No need to worry about the 2GB vram , the 670 and 680 show that they perform close to or better at times against the 7950/7970 3GB vram depending on the game in the reviews.

Go with the Gigabyte Winforce 670, both your choices are good , but I prefer the Nvidia drivers.

DM186 is right , there are too many posts about the 7970 on here with problems.

Thanks for the comments guys, Its been really helpful.

Yeah I decided to go with the GTX 670 for the time being (hehe to bad it took me so long to decide, Out of stock now, so will have to wait abit, but its okay with me), and hopefully in future the Vram won't be a bottleneck.

What you think of the remaining components, just to check they are all compatible with each other right:

CPU: i5 3570K
HSF: CoolerMaster Hyper 212 EVO CPU Cooler
GPU:Gigabyte GeForce GTX 670 OC 2GB
MB: ASUS P8Z77-V PRO
RAM: Corsair Vengeance CML8GX3M2A1600C9 8GB (2x4GB) DDR3
PSU: Silverstone Strider Plus 850W ST85F-P
Case: Corsair Carbide 400R Black Mid-Tower Case

Is that a quality power supply, and in future will it be able to run 670's in SLi if i need it?

Will be looking to get an SSD in the future.

Any suggestions?

Great set up , that psu is perfect for your build if you want to go SLI in the future.

Grab an SSD for sure , check out the Samsung 830, Crucial M4 and the Intel 520.

Either one of these are a good choice for SSD.

Yeah I have to agree with monsta you can't build much better then that one. With the 670 on board then you will be able to handle anything thrown at it. All games on ultra. Pat your self on the back you deserve it.

I thought newegg had a bunch of them yesterday now they are all gone except one the EVGA one but it to will be gone by tomorrow. This is the only one left in stock.

Thanks for all the help guys, you indeed have really helped me in deciding here, so I appreciate the time and effort you put into commenting.

Yeah for my brothers build about 3 months back I got him the 7950, so i guess I'll go with the GTX 670 and see how it perform in comparison to his in the long run.

monsta and DM186 you two have been extremely helpful (along with the rest ofcourse) so I want to thank you.

DM186, im in Australia, so can't buy from newegg. Also I want to get all the stuff locally for my first build so if anything screws up, I can RMA it much easier and cheaper. However as I gain more experience I will look abroad to Amazon and the like to hopefully get better builds for cheaper. I will be getting mine from Pccasegear, and thankfully they will likely have the Gigabyte 670 Windforce back in stock on the 21/05/12 so that's great if i want start building soon.

monsta since your from Oz, just wanna ask you, have you bought computer components from abroad? and if so had any bad experiences with the products and had to RMA any.
