HD7970CF or GTX680?

post #1 of 11
Thread Starter 
Hello guys, I bought the HD7970 on release date and was planning from the start tog get another HD7970 for CF, should I buy the new GTX680 and put it in SLI later or get another HD7970 and CF them?, and will it be long untill GTX690/700 (Dual GPU`s) shows up?.

Thx for the help guys smile.gif

P.S I can afford to get GTX680 SLI or get another HD7970.

I play in a resolution of 1920x1080 and the reason I want SLI/CF is because i cant stand to play games under 60FPS wich is a minimum for me (FXAA on).

And the GTX680 would also make me able to play games on my monitor in 3D.

Both cards are really fast and expensive, your going to be able to max out anything on either setup. So at this point it's what brand you like and $$$. The 680 GTX is $100 cheaper then the 7970. Both perform fast and about the same give or take a few FPS either way. There might be fan boys on either side that disagree but I believe they're both really good and the 680 GTX winning in the $$$ department.

SO if you already have 1 7970 then why not buy a 2nd for less headache in having to sell a 7970, Or sell your 7970 loss a $100 (but that's the price difference) and buy 2 680's. You doubt you will see any difference in performance when running you games on ultra settings.

Before you decide on which way to go, I suggest that you read this AMD biased site's review:
http://hardocp.com/article/2012/03/28/nvidia_kepler_geforce_gtx_680_sli_video_card_review

I point out that they are AMD biased for many reasons, but more importantly, for them to come to those conclusions makes me think you are better off with GTX 680 SLI.
Quote:
SLI smoothness vs. CrossFireX smoothness
We don't know what other descriptive word to use, other than "smoothness" to describe the difference we feel between SLI and CrossFireX when we play games. We've expressed this difference in gameplay feeling between SLI and CrossFireX in the past, in other evaluations, and we have to bring it up again because it was very apparent during our testing of 680 SLI versus 7970 CFX.

We can't communicate to you "smoothness" in raw framerates and graphs. Smoothness, frame transition, and game responsiveness is the experience that is provided to you as you play. Perhaps it has more to do with "frametime" than it does with "framerate." To us it seems like SLI is "more playable" at lower framerates than CrossFireX is. For example, where we might find a game playable at 40 FPS average with SLI, when we test CrossFireX we find that 40 FPS doesn't feel as smooth and we have to target a higher average framerate, maybe 50 FPS, maybe 60 FPS for CrossFireX to feel like NVIDIA's SLI framerate of 40 FPS. Only real-world hands on gameplay can show you this, although we can communicate it in words to you. Even though this is a very subjective realm of reviewing GPUs, it is one we surely need to discuss with you.

The result of SLI feeling smoother than CrossFireX is that in real-world gameplay, we can get away with a bit lower FPS with SLI, whereas with CFX we have to aim a little higher for it to feel smooth. We do know that SLI performs some kind of driver algorithm to help smooth SLI framerates, and this could be why it feels so much better. Whatever the reason, to us, SLI feels smoother than CrossFireX.

Personally speaking here, when I was playing between GeForce GTX 680 SLI and Radeon HD 7970 CrossFireX, I felt GTX 680 SLI delivered the better experience in every single game. I will make a bold and personal statement; I'd prefer to play games on GTX 680 SLI than I would with Radeon HD 7970 CrossFireX after using both. For me, GTX 680 SLI simply provides a smoother gameplay experience. If I were building a new machine with multi-card in mind, SLI would go in my machine instead of CrossFireX. In fact, I'd probably be looking for those special Galaxy 4GB 680 cards coming down the pike. After gaming on both platforms, GTX 680 SLI was giving me smoother performance at 5760x1200 compared to 7970 CFX. This doesn't apply to single-GPU video cards, only between SLI and CrossFireX.

Crossfire 7970 is supposed to be horrible atm driver wise, if you go to the 7970 owners thread you will see so many complaints, I have seen no complaints from 680 sli people yet so sell the 7970 for a small loss and go for a 680 =)
post #5 of 11
Also you should really take advice from people who own that tech there's to many people that give opinions on this and don't own a single 7970 or 680. I own 7970 x2 with 2600k and there's no issues very fast, the 680 also very fast there both expensive fast cards your going to get the performance either way. I can tell t you this from being an owner.

EDIT:

Sorry i was getting my information from various reviews online and never bothered to check the stores for pricing. In Canada the 680 GTX is going for $509 at the cheapest on sale (Just like the 7970's did when they first came out), after the sale the prices, the 680 will be $549+ so for now they're $40 less and when the introductory sale is over the price will be the same. Im a little let down by this first blatant lie i've read on multiple reviews claiming the 680 GTX is $100 less making it a better choice, they didn't hae to lie because the 680 is a good card but if they were wrong about that what else were they wrong about.

Currently running 2 x MSI Reference 7970's @ 1200 core/ 1650 Memory. BF3 and Metro 2033 are butter smooth ( 1920x1080P ). Currently using 12.3 WHQL Drivers with no problems, my vote is for a second 7970. Once a pair of 7970's are overclocked to 1200/1650 I don't think a pair of 680's have much on the competition. Good Luck with your choice thumb.gif

I dont think you need CF or SLI for 1080p unless you want to achieve 120fps for 120Hz screen.

HD 7970 over clock to
1290mhz memory 1800 max out BF3 average 70+ FPS.. most of the time at 80 or something.

I can honestly say Xfire is really bad...... Stick to one card for 7970. I don't have 680s yet but I did owned 580 sli while it's better in most cases I truly felt single card is the way to go to avoid any bashing and headaches with newly release games.

I don't think u need that much power anyways it's better to stick to one card and just buy a new card down the line when it's release.

IMO if you already have a seller for your 7970, sell it, and grab 2 680s.They will both perform around the same.

7970 has 3GB of VRAM that will help with higher resolutions, but in all seriousness, people are over dramatic about running out of VRAM, I ran a 570(1.2GB VRAM) SLI setup on 3 1080 with maxed VRAM all the time, it was not a big deal. But I get better frame rates from a single 680 than my SLI setup. thumb.gif
