6970 Crossfire vs GTX 580 SLI - Page 9

post #81 of 109
plus if you actually tally the number of times 6970s gain any advantage in anything bellow 2560x1600 in the benches he showed... you'd see that 580s are pretty much the clear cut winner.

6970s may win in higher res situations but if you look at vega's thread on xtreme system... he tests both 6970s and 3gb 580s in sli/crossfire extensively and the 580s come out on top . IT might not be the best price: performance, but they are what they are.

Mate i never said anything about 6970 beating a 580 single card wise. Re-read my post again, in 2 way setups 6970xfire and 580 sli are very similar performance wise whether you like it or not. All i said was max OC on both setups in sli and xfire the 580 wins because they gain drastic performance when clocked. I do prefer 580 sli but only if i had the money would i buy them

A 580 at 900 core will beat a 6970 at 1000, given these are the typical overclocks you would expect. Difference i would imagine would be quite noticeable
that was what i was disagreeing with... at stock they are not about the same in most games. They are about the same as two 570s, not two 580s

they are alot cheaper though

EDIT: and if you reread my post i mention 6970s with s conveying plurality

Blah blah blah, the OP already made his decision on the FIRST page. For this thread to continue yet another EIGHT pages where it did not even help the OP, but only fill your egos is really pathetic.

Urbanshaft and IBM Watson: You two are technically "new" here with such low post count and rep. I'm not saying that post count and rep is what makes a person here, but most members here would rather listen to editors and members who have thousands of posts and years of experience on OCN versus a couple of "newbies" that keep wanting to jam crap down everyone's throats. The sad fact is that neither of you have the gpus mentioned by the OP, so why bother?

I'm just gonna pretend i didn't read this thread..

But to 45nm though..
Ultimately the 580s would be better than the 6970s.
But comes at a price, Now lets look at the pros and cons of the 580s and 6970s

GTX 580 SLI
PROS
- Very powerful, Beating the 6970s in benchmarks and games
- Smaller in size compared to 6970
- Better driver support

CONS
- Price, for the same price you can get 3x 6970s which would be more powerful than Dual 580s
- Heat, nVidia cards get really hot, Limiting their overclock ability
- Lack of VRAM
- High power consumption


Radeon 6970s Crossfire
PROS
- High amount of VRAM, Better for higher resolutions and more monitors
- Eyefinity allowing multiple monitors
- Better scalability
- Low heat, Great for overclocking
- Less micro-stutter than dual 580s
- Less power consumption
- Price, Much cheaper than dual 580s

CONS
- Lack of driver support
- Less powerful than Dual 580s
- Size, Huge in dimensions

There is probs more but can't think of anymore

Most sums up to price, For same price as 2x 580s you can get 3x 6970s or 1x 6990 and 1x 6970.

Eyefinity also comes into play, Getting a third monitor would be great for FPS gaming, And eyefinity will help your 2 monitors.

I'm not gonna say get this or that but i will let you decide.

Single card wise the 6970 is around a 570 for sure but not in xfire. check your facts again. It really depends on the game though, but difference is not astronomical between these two on the games one beats the other anyways. Im saying on average the two setups are somewhat similar. Its hard to say the a pair of 580s beat the 6970's downright.

LOL! 580 SLI is so much better then 6970 Crossfire!!!!.... NOT really...

I love that slide.

1000$ for that? Chocking badly on a triple monitor set-up! And the 2X 580 3Gb SLi is not that better. Actually, the 6970 Crossfire easily keep-up with it. But the 580 1.5Gb SLI is an OVERPRICED POS.

Honestly. People are paying 1000$ to get that?

And for the price of 2X 580 3GB, you could get 3X6970 that would kill the SLI set-up.

OP, I am sure you will love the cards,

I have two of them and the 1000K will be fine and there is nothing they won't do for you in the gaming department and lots of fun to bench as well.

HAve fun and enjoy cutting edge preformance..........................

Lot of hostility in here for some reason

Well the guy decided on 2 580s, good for him.
The research I did when thinking of getting my card (570) led me to believe 6970s xfire and 580s sli were quite similar. Was going to pull the trigger on a 580 with the view to get a 2nd at some stage. But the price and having less VRAM I decided to go with the 570.
AMD have really given Nvidia a run for their money with scaling. 6970 is for sure less powerful than the 580. But 2 together there is very little in it
post #90 of 109
In terms of drivers, the ball is still in nvidia's court. Drivers for amd are much more involved, needs more tweaking and adjusting to get the most out of your cards. Still was true when I had my 48xx series and with my current setup. Eyefinity is also very finicky to work with. Nvidia's drivers are much smoother, easier to work with and surround is simple to setup.

I decided on my setup because its one of the best bang for your money. Though its not perfect, but honestly neither is Nvidia

Good luck with your choice.
