Default MY questions about SLI GTX570 or CFX HD6950

Hi,

I would like to know if the famous "stuttering" is gone with today's multi-GPU configurations?

Also, is using two cards will likely increase minimum FPS in most games, or it just affects max FPS?

Thx! I'm still hesitating...there is such great reviews of HD6950 CFX, it's almost too good to be true. Same to be said of the GTX570s in SLI...

I'm looking for a little overkill on a single monitor at 1080P (my single HD5870 would probably be fine already...! If it's not valid points, I'll settle for GTX580 or HD6970 I guess

There is got to be some HUGE HYPE or something, because dual card reviews are awesome, but AMD/ATI forum has a lot of people with issues, with minimal support from AMD...

Well, nVidia doesn't have a stutter problem in any games I've played. I can't confirm anything an ATI, but it sounds like it's getting better or may be fixed. Value wise, the 6950 scales better than the 570, so the 6950 is a much better route unless you need the extra processing power of the 570.

After switching over to a single GTX 570 on 1920x1080, the only games that I don't always get 60 fps: Metro 2033, Just Cause 2, Mafia 2 (physX on), StarCraft 2 (enthusiast settings 3.8 Ghz i7-930). I find all of these games are [very] playable at max settings, although Metro 2033 is on the fence for playable.

I do not support spending more than the price of a single GTX 580 for this resolution, but I might make a concession to the 6950 2GB (versus the 1GB model) if the 1GB model does not scale as well as they 2GB model, OR if you know you want to go 3-way down the road and tack on more resolution. SLI GTX 560 will outperform the 580 by about 25% on average, and 15% on the low end, so that's a better option than the 570.

Still, I can't recommend paying a $100-140 premium for the 580, but I highly suggest getting a single card set-up as it's really ******* annoying to run into games with poor SLI scaling or other problems (i.e. Just Cause 2 disables SLI scaling when you have a dedicated PhysX card installed...)

I loved getting my 6950, however after multiple crashes and stuttering in SC2 , EVE etc I have come to the point of almost giving up on it.

Go with the 570's as you'll find that the driver support should be much much better than the issues I am dealing with.

K,

So I have a few options basically... 2 X $340 ($680 for 2 EVGA GTX 570)

or

2X EVGA GTX560TI ($250 each for $500) or ASUS DirectCU II at $270 each (too bad it"s the price of a HD6950 2GB)

or

1 X EVGA GTX580 at $499....

Tough times...this gonna sit on a P67 platform with an OCed 2500K or 2600K at 4.4GHz to 4.6GHz

I have a 6950 and have had no issues with it at all, its BIOS unlocked to 6970 and overclocked to run at the same speeds, works very well and I am very happy with it.

If you find the ATI route doesn't meet your need, pricing (if you shop around and catch sales) for the nVidia camp are as follows:

GTX 460 1gb - $170
GTX 560 Ti - $230
GTX 570 - $310
GTX 460 2Win (dual 460) - $430??? MSRP (new card from evga)

GTX 570 - $310
Show me! The cheapest lifetime warrantied 570s are the Zotac, that come to $310 AFTER MIR...
Then, you get EVGA "glory" for $340 PMed...

I've seen some MSI "reference" cards with OCed BIOS, but there is a LOT of people having issues with unstable cards...I guess MSI should sell cards at stock clocks...

I might go back to the green team...I love my HD5870, and the HD5770 from the kid's rig..don't get me wrong... I have to agree that Hd6950 pricing is really appealing.

I really want to go dual-cards (my first try) but I'm scared of stuttering...REAL or RUMOR? Some people say that stuttering is REAL but unnoticed because of being concealed by high FPS...

when you can get 2gb 6950's(unlock or not,who cares) for 270 or cheaper with mir, 310 for a 570 is a joke :)
