^^^^^^^^ in most games ? I expect it will run really hot and noisy tho, even without side panels on my case

Depending on the resolution. 1080p you dont really need it for most games.

I've seen some benchmarks and it at 4x it doesn't seem to have much of an impact on performance. I'm not really having problems with crossfire, just that lots of games that I play aren't really compatible or just don't go beyond 60fps. My CPU is probably the limiting factor in achieving 144hz.

it used to work but not for any upcoming titles so NO ABSOLUTELY NOT!!!

and in the future

MOST LIKELY EVEN MORE ABSOLUTELY NOT THAN NOW!!!!

Let me explain...

NVIDIA is backing and dumping more and more money into titles... I believe that this leads the developers to have an attitude that now in order to be bug free and work perfectly that the manufacturers should be paying them and doing the beta testing for them. This is crazy! But it really seems plausible.

UBISOFT

Far Cry 4 - NO crossfire support
Assassin's Creed Unity - NO crossfire support
Dying Light - Very very poor to no compatibility with poor scaling. (the game flickers in shadows and has a very small increase in performance even if the CPU is not bottlenecking it, I am running 4.8GHz Haswell!)
Watchdogs - "supports crossfire" never really got it to work smoothly and it certainly didn't work even close to smoothly when it first came out. When it first came out my GTX 690 and SLI GTX 580 based rigs worked much better.

Evolve (I don't own this but) LINK TO PEOPLE COMPLAINING ABOUT CROSSFIRE NOT WORKING!!! I know for a fact it works with NVIDIA as of their driver update on February 10th.


I have not bought a SINGLE game in the past 6 months that works and scales with crossfire.

YES there are games that have come out in the past 6 months... I am just saying NONE of the titles I have purchased have been ones that crossfire has been both usable and made a more than 20-30% difference in frame rate

WHY IS IT GOING TO CONTINUE TO BE THIS WAY!!!!

This is actually simple to answer. With the launch of the AMD Omega drivers AMD has hinted at driver launches that are quarterly based! I didn't think that they meant NO BETA and NO DAY ONE but apparently they did! Drivers came out 12/9/14! In two weeks that will be 3 months... most likely drivers will not come out until they are ready to ship the 380 and 390 samples to reviewers.

NVIDIA mean while is doing day one driver launches on important titles as they have always done. Dying Light received a DAY ONE beta driver! "GeForce Game Ready Driver WHQL 347.25 January 22, 2015 - Best gaming experience for Dying Light" and then again "GeForce Game Ready Driver WHQL 347.52 February 10, 2015 - Best gaming experience for Evolve, including support for SLI Technology and GeForce Experience 1-click optimizations"

For Dying Light my single GTX 970 gets better performance than my (2) R9 290X even with crossfire turned on and the annoying shadow flickers present!

My recommendation is this...

Instead of buying another R9 290 sell it on ebay in a month or two and buy a 380X. It will be faster than an R9 290 and it will work with ALL GAMES!!! NVIDIA is a wretched horrible company who lies and does shaddy things to lock people into their products just like apple does. GSync will fail in about 2 years (or less) and NVIDIA will enable AdaptiveSync/FreeSync at that time. NVIDIA has already put a laptop on market that supports AdaptiveSync eDP with the use of an older beta driver and then they yanked the function away probably of fear that people would realize that it was doing this without the use of a GSync module or maybe because they are afraid it might allow the laptop users to use AdaptiveSync enabled external monitors and then everyone would know that GSync is bull!

For that reason I wouldn't touch NVIDIA if I where you. So stay with AMD they are an honest company with a great value... Just I guess they don't have the money to be throwing cash at developers... Or they think it is immoral to do that... I don't know there reasoning for leaving us all hanging without any crossfire support for over 6 months but it is what it is.

People will no doubt flame this but its the truth... Unless you have some very specific games in mind and don't plan on buying any new games in the future stay away from crossfire.

BECAUSE - I have not played FarCry4, Dragon Age Inquisition, or Assassin's Creed Unity for a while I am going to re-check those games to see how well they work with crossfire. I think DA:I did work but didn't scale much.

I can only PRAY that Grand Theft Auto and The Witcher work with crossfire but I think it will have to do greatly upon what comes first. The game or the new Omega patch. If the patch comes first I fear the games will fail to be supported well. If the patch comes within a week of the games dropping then again I don't think it will support them since they will already have closed off any major changes and reserve changes only to major major bugs.

AMD has truly turned it's back on its 295x2 owners and the entire enthusiast crowd! Their fastest card is the fastest card. It will remain the fastest card when the 390X drops but unfortunately in most games it is only half its speed or barely any better than half.

Just to make sure I'm not the only guy having issues with ALL new games but do you know of ANY newer benchmarks showing NEW games that show 100% compatibility (no shadow flickering) and 80-100% performance gains and no stuttering?

W/ my motherboard I have the choice of running my cards in PCIe_16x@3.0 x2 (using PLX) or PCIe_8x@3.0 x2 neither configurations run well on most new titles. Early and mid 2014 titles and everything before then run perfect with great scaling performance. If I don't see 80-100% scaling then there is a frame cap, vsync, or CPU bottleneck.

some people gets gain in some games with an i7 (when they support 4+threads) with a 290 cfx

What games...

I have a i5 in this system but have an i7 available. The reason I don't use it is because there are a maybe 2-3 games I have seen minor gains in. Anything under 5% doesn't count since for every game that an i7 is 1-5% faster there is a game where the i5 is 1-5% faster.

I have indeed seen at least 2 games where an i7 made a minor difference but if I swap in my i7 then almost all of the games I play will perform worse since I will be going from a delidded 4.8GHz i5 that is capable of more to a non delidded i7 that can barely handle 4.5GHz.

I'm selling everything I have right now to move to the cheapest 6 core i7 and eventually an 380X and then after I already own a FreeSync monitor then MAYBE just MAYBE I'll buy a second 380x but more likely I would sell the 380x and buy a 390X depending on price of course. Obviously if I can have (2) 380s for the price of (1) 390x then... well nuff said.

Anyways let me know if you know of any benchmarks...

I have a i7 920 and xeon w5590 and several other CPUs laying around. I just have noticed that they don't come close to my i5 4.8 in games. Like I said plan is to sell everything I have off and buy 16GB of DDR4, the cheapest 6 core x99 bundle microcenter has ~$500 w/ motherboard and then I will be done with it... No more worrying which is better i5 at 4.8 or my 1150 i7 at 4.4 - 4.5GHz or any of the many 1366 processors I have.

well when I mean core i7 should be SB/IB/Haswell /-E

BF4,Crysis 2,Crysis 3,FC3,Arma III,TotalWar RomeII/Attila,Evolve,are some examples,check gamegpu.ru for more

And games would become more multithreaded given the low level apis like mantle and directx 12

I have two R290s and they are great. I mainly play BF4, the Mass Effect series and now Dragon Age Inquisition. Looking at the GPU usage during gaming its using around 80-90 percent. I get very good frame rates with everything maxed out.

I play DA:I too and works great. On mantle works even better.

Your HT link if stock is also at 2400MHz. If that is the case,try raising it. You are generally leaving considerable xfire performance on the table with a 970 chipset.

Thats strange, running DA and BF4 in Mantle causes all kinds of weird issues for me. DA I get some random texture flashings and in BF4 it just crashes after about an hour and It needs a reboot to work agian... I have removed and reinstalled the driver a few times already.

your cards/drivers should be the problem because bf4 with mantle work great.or maybe you use ulps or your cores are parked

I agree with you. I own 2 Sapphire 290X Vapor-X 8 GB and in recent games, my 2nd GPU is "sleeping". But I tested 2 GTX970 in 3840x2160 and I encountered many bugs on a few games : Crysis (bad stutters)...Conseuqently, I returned them and kept my crossfire. Unfortunately, the 4K resolution won't be playable until at least 3 years, at 60 fps with a single GPU.

For crossfire owners, the situation is not satisfactory but let's see if the next Catalyst update confirms your assumption.

For crossfire owners, the situation is not satisfactory but let's see if the next Catalyst update confirms your assumption.
With the GTX 970s your issue may have been that you where exceeding or approaching 3550MB so to compare them to the 290X you have to run them at 1 step lower texture settings... so like high instead of ultra or medium instead of high. Since it seem that the AMD drivers and the games know what to do when approaching the 290s 4GB limit but they don't know what to do with the 970 since they think the 970 is capable of using 4GB where I have actually seen on my 970 that the second it hits 3550MB its dead! Unplayable!!!

Check if your cards are throttling and check the temperatures,you have ulps enabled as default,and if you are on windows 8.1 the cores are already unparked.

Or maybe it is the game that has vram leakage

Im thinking the game, its been noted by others of an issue running under Mantle. Ill try the ULPS and see if it gets me some performance in DA. Im seeing temps max out around 80C on the primary card and around 70C on the secondary with 80-90 percent usage
