Don't call it misinformation. It's a matter of opinion on what ones eye sees compared to another person's. This is with me ignoring the fact that there is relevant data to back up what people say. As stated in my first post, it's subjective to a person's opinion whether or not they will notice any stuttering or not. Doesn't mean your rig stutters, doesn't mean it doesn't stutter, just means you may not see it but someone else might.

There really is no flame fest as long as people don't make stupid comments.

If you're going to go multi-gpu, go SLI. Crossfire to 660TI's and they perform better than a Titan at half the price. 'nuff said.

I ordered second 7950 just because i know that there is new drivers incoming, and for the price, there is not simply better performing setup for 1440p screen. Also i have seen 7970 CF setup with 13.3 beta drivers in action, and i can say its far from "unplayable". Whoever is planning to buy CF setup, do not just look the diagrams how the latency is, it makes everything look ridiculously bad. But yeah if you are planning to game on with latency meter + -50% slow motion speed, do not get Crossfire setup. Not to mention when these things work 100% both on average console port, it gives major asskicking to half more expensive GTX Titan.

I've only really noticed stutters at very high fps for example blop2 when I'm at a constant 200fps since I got my 1440p monitor I haven't noticed any stuttering since my overall lower fps has been down.
I thought it was said with vsync enabled the stutter was next to unnoticeable within all games but I could be way off base of the that one(could of sworn I read it in one of the articles though).

Microstutter is inherent to every multi gpu setup, But people are over stating the amd microstutter and PCper are almost entirely biased from anyone whose viewed it objectivly, The whole microstutter frame time thing only recently became a fad and well they are at the very center of it heralding Nvidia to be the be all and end all, It's like tomshardware and PSU reviews, Truckload of salt required.

OP the HD 7990 is launching on 24th april with the 13.5 beta drivers . there are crossfire optimizations and the new memory manager which resolves frametime deviations and reduces stuttering. the complete solution for CF issues with frame pacing is supposed to take till July.

I would suggest a single HD 7970 or HD 7950 now and a second one when AMD resolves the CF issues in July. thumb.gif

I have dual 7950's and the only game I have a problem with is Far Cry 3. Every other game runs fine. Maybe I'll get a stutter every once in a while when entering a new area of a map, but it is just a quarter of a second and it doesn't bother me at all. Games like Crysis 3 run butter smooth. I guess that's just my experience with it. RESULTS MAY VARY

Older GPU usually scales very well because of mature driver, but new cards usually gets higher FPS with less power consumption compared to previous generation.
Most of time CF/SLI works great without problem, but it generates too much heat for me.
Single card solution is always better than CF/SLI, but getting a single card that performs equal to CF/SLI card cost a lot of money. For example, you can buy 7870 tahiti LE crossfire set up for $450 that equals gtx titan performance that cost over $1000. My only option was to go CF/SLI for higher performance. If gtx titan was below $500, I would probably grab that instead.

um... there's no misinformation. I'm just pointing out the facts discovered in the article I linked in the OP. I'm not trying to start any kind of flame fest, I'm not at all trying to start a debate about whether Nvidia or AMD is the better GPU maker and I'm not even trying to compare SLI and CrossFire. I'm just looking for information and suggestions, because I typically lean towards AMD cards when GPU shopping just because that's why I'm familiar with, and I'm interested in doing multi GPU.

edit: so to answer your question . . . i say - yes.

Not for Far Cry 3 maxed out, and most certainly not for Crysis 3 maxed out. Hell I can't even play Sleeping Dogs with high settings (I'm not even talking maxed ultra) without dipping below 60. I'm also trying to future proof for games like BF4, which was apparently run on a 7990 during the 17 minute demo and there are some very obvious stutters.

THANK YOU! This is the info I was looking for. At least they have something in the works for the near future. I don't trust AMD's promises enough to go ahead and buy both right away, so I think I'll do what people are saying and get the first one now and get the second card this summer after I see proof the CF issues have been fixed.
