your link says your cpu speed is 2147483647 MHz ***
that 2500k of yours should be smacking the crap out of my i5-750 even at 4.2ghz , I think your score should be higher than that dude i dont know whats up with your rig.
the 7970 i had surely does not ever beat my 670 at least in my rig, i tried like hell to beat my old gtx 470 sli record for myself with the 7970 and FAILED heres the link
edit: furthermore if I had paid $399 for the 7970 , i would have kept it , however at the time it was $599 and i didnt feel it was worth it. Now i have the 670 and it performs better in MY rig , and for $399.

Thats weird because when i saw it the first time it was 4ghz vs 4.2GHz, hmmmm....

I dont think theres something wrong with my 3dmark score both cpu/gpu have mild overclocks on them... theres nothing out of place on those scores. One thing for sure is just a synthetic score i only use it to compare it to "similar" setups... I would be worried if with those clocks i were on the low 8k or even 7k point range.

I can tell you one thing for sure overclocking the memory on the 7970 the gains are so little that is not worth it, plus is the main culprit on instability, so i just compensate a little to match the core clock speed..

About my cpu speed there, dont know what the hell XD always appear like that..

Breaking down the Vortez Reviews:

7950 page
670 page

Some notes:
  • Both cards are reference models.
  • They used the exact same test system for both reviews, the only difference being the motherboard (ASRock X79 Extreme4-M for the 7950 and MSI X79 Big Bang X-Power II for the 670, they're both X79 so there shouldn't be any significant difference in GPU performance).
  • They're using rather old drivers for the 7950 as the review was written in January 2012, but since the 670 just released and hasn't been able to benefit from driver improvements yet, it should be pretty fair in the long term.
  • All of the benchmarks are using the same in-game settings.
  • The 7950 is overclocked to 1041/1419 and the 670 is overclocked to 1200/1555. Given my assumed averages for both (7950 average = 1100; 670 average = 1300; ratio of .85 to 1], i think these are very reasonable numbers [reasoning: 1041/1200 = .87; so the 7950 is slightly ahead when compared to my average ratio, by ~2%], especially given the fact that they have very similar overclock scaling.

Game Benchmarks:
For each game i will only be looking at the overall performance as i think this best represents each card for the majority of people looking for a single card for the 1080p to 1600p resolution range.

In all games, the first number under each game will be the 7950, the second number will be the 670.

Battlefield 3:
62.25
70.21

Crysis 2:
56.85
53.09

Crysis Warhead:
48.78
48.35

Metro 2033:
28.75
33.25

Skyrim:
103.82
108.79

Batman:
46.75
56

Dirt 3:
79.59
93.75

Averages:
Total 426.79 / 7 games = 60.97 fps
Total 463.44 / 7 games = 66.21 fps

The 670 is, on average, 8.6% faster than the 7950 in games at 1080/1600p with 0xAA up to 4xAA.

Synthetic Benchmarks:
3dmark11:
Performance:
8538
9680
Extreme:
2901
3160
Average:
5719
6420

Unigine: Heaven 2.5
1080p, 0xAA:
1785
1958
1600p, 4xAA:
888
871
Average:
1337
1414

Average for both synthetics:

3,528
3,917

The 670 is, on average, 11% faster in these two synthetic tests at performance (1080p) and extreme (1600p with 4xAA) settings

Overall Conclusion:

The 670 is ~10% faster than the 7950 when they're at comparable overclocks at 1080p with 0xAA up to 1600p and 4xAA.


Closing note for the haters and fanboys of both camps:
This is not my personal opinion, this is just what the data from this particular website tells us. I do not know the legitimacy of their findings, so it's up to you to decide if you wish to believe this information. And please, don't attack me on a personal level like has been done in the past when i've done a comparison like this. If you have issues with these two reviews, go complain to vortez.net teaching.gif

Thanks.. so here's a question for you -

7950 (Sapphire) $450
Asus GTX 670 TOP $425 ish?

Which card would you get for 1080P if price wasn't an issue since they're close enough for me not to care..

I'm inclined to want the 670, but they're kind of hard to choose between - the extra VRAM would be nice for heavy modding in Skyrim or GTA IV - but I think Nvidia does better in both these titles vs even the 7970 anyway so I'm not sure how much of a difference it will make at 1080P

Yes I plan to OC.

The 670. VRAM has really no benefit under 1600p in modern games. Even Skyrim with pretty much every demanding mod only uses 1.8gb at 1600p with the game completely maxed out.

Cool, because I want to go to the green side this time! I figured I'd be fine at 1080P - hopefully I still will be 10 months down the road. smile.gif

Edit: Yay for 420th post!! If you know what I mean... Time to go devil.gif

the choice is yours as to which card you want to pick. But try and have a look at the Sapphire HD 7970 OC at USD 449. its a beast. And never underestimate the games coming down the road in 2012 and 2013 in terms of how demanding they can be on bandwidth and VRAM thumb.gif

"The NVIDIA GeForce GTX 680 had a hand up in performance on the stock Sapphire HD 7970 in every game. The Overclocked Sapphire HD 7970 OC Edition crushed the GeForce GTX 680 though in every game providing the best performance and gameplay experience. "

I have two problems with the 7970, however.. well maybe more than that. One is that I have an 850W PSU and I'm not going to comfortably run xFire with two 7970's on that PSU especially if Piledriver doesn't flop and I decide to buy one and OC it.

I'm not happy with xFire / driver issues right now from AMD.

I know the 7970 OCing performance is excellent, but I don't want my fans running at 70% or even more in xFire to keep the OC cool, stable, safe, etc. I also have a small room and the extra heat is a real bummer when the AC bill comes in.

I'm pretty sure I'm going to go with a 670 Asus TOP card.. possibly SLI 4 months down the road - which means I might consider waiting for 4GB SLI BM's.

for a single 1080p monitor why do you need multi GPU. HD 7970 OC is going to max out any game and give you 60+ fps. Even a stock voltage OC to 1150 Mhz is going to be more than enough to achieve 60 fps even in the most demanding games. anyway if you have made up your mind go ahead. enjoy your purchase thumb.gif

Well I said 4-6 months down the road.. I wouldn't doubt I could find something to do with all that horsepower by then.

I'm looking at single GPU right now, multi GPU is a future consideration.

A higher resolution monitor is also a future consideration.

This HD 7970 OC card is shown to be playable in BF3 at 2560 x 1600 with Ultra 4x msaa

http://www.hardocp.com/article/2012/04/10/sapphire_hd_7970_oc_edition_video_card_review/7

At 1125 - 1150 Mhz at stock voltage this card should do 45+ fps with min fps > 30. So I still don't see need for multi GPU. Also even if you are looking at multi GPU 6 months down the road I feel the driver situation is going to be much better. just my opinion. smile.gif
