Hi guys, I am new in this forum, so hello everybody and nice to be here :) The thing is: I am going to build a Gaming PC, using Asus Crosshair-V Formula-Z as the motherboard, with 32 gb of RAM running at 2400Mhz and a 4.0 Ghz, 8x core AMD processor, and my doubt is: Is the AMD Radeon HD 7990 compatible with all this components (specially with the motherboard)? Will I have any problem running it without Crossfire at ultra settings at 1920x1080?

Thanks a lot for your time!

See you!

7990 absolutely must run crossfire as it is a dual GPU card. And, yes, it will run max settings on pretty much any game at 1080p. I would even urge you to save some of your money as what you plan to build is complete overkill for 1080p gaming. Do you plan on doing multi-monitor or 1440p+ in the future?

Yeah all that should work fine together.

AMD Radeon HD 7990

Asus CROSSHAIR V FORMULA-Z, it is a crossfire ready board. Don't worry if it doesn't have Pci express gen 3. The 7990 can't even fill up Pci express gen 2 X16 lane.
http://www.asus.com/us/Motherboards/CROSSHAIR_V_FORMULAZ/

32gb of Ram, high overclock on the memory, the board should be able to handle it. And from what I understand no game will use 32gb yet. 16gb should be more than enough. If you have the money to burn and just wanna max out your memory go ahead. Be sure to use low profile memory so you don't have Cpu cooler fitment issues.

Amd 8350 Cpu right?

You should be able to run anything at 1080.

You sure you need a 7990? If you are doing 3 monitors in the future you should get it.
You could do just as well with a 7970 if you are only ever gonna run a single monitor.

What cpu cooler are you going to use?
I would suggest something from Noctua, their cpu mounting solution and installation are really easy and the quality is top notch. A little pricy though. Cheapest place for Noctua cpu heat sinks I have found

What case are you going to put all this hardware into?

If you do downgrade the ram to 16gb and to a 7970, you should consider spending the saved money on the biggest SSD you can afford. I would suggest a Samsung SSD or a Crucial M500 SSD.

Hey, thank you very much for being so quick! Actually, I got a 2560x1440 monitor (achieva shimian qh270-ipsms), so I will play at 1440, and I thought about the multi monitor, but I have doubts about it, don't know if I´d like it... (What do you thing?) I will first try the 7990 with a single monitor and depending on how I feel, I will go for another monitor, don't know yet...

Hey, thanks for being quick man!!
Well, I was worried about the 3rd gen.. but now that I know there is no problem with 2nd one, OK :).
Don't worry about the money, no problem with that, I've been saving for long time :p

Well, you got it, the AMD 8350. Actually, I was thinking about the Corsair H110, water cooling, do you think that will work? Or better a Noctua one?

The case: Cm storm stryker

About the SSD, I already got the Samsung 840 SSD series 500 gb SATA 3 plus 6 tb of HDD.. I Know it is crazy, but kind of want it.. :S

By the way, what do you thing about this? http://www.newegg.com/Product/Product.aspx?Item=N82E16817121068 Any other suggestion?

P.D: I am planning the 7990 because I might put more than one monitor, but still have doubts about it...

Thank you very much buddy! :)

Hey, thank you very much for your recommendations, I will take it into account, I think I will go for the 850w you said, http://www.amazon.com/Corsair-Professional-Watt-Modular-AX850/dp/B003PJ6QW4/ref=sr_1_3?s=pc&ie=UTF8&qid=1376874065&sr=1-3, and do you think it will be enough? what about this one?: http://www.amazon.com/Corsair-Professional-1050-Modular-HX1050/dp/B0090I9VVC/ref=sr_1_3?s=pc&ie=UTF8&qid=1376874168&sr=1-3

Yeap, you just guuessed the card I was going to buy.

Thank you very much, see you!!!

If you want a closed loop water cooling solution, the Corsair H110 should perform well.
My only question is will it fit in the CM Storm Stryker? You need a 140mmX2 (280mm) fan mounts with the right spacing.
l

If you don't plan on going nuts overclocking, air cooling from Noctua will work just fine, and you don't have to worry about leaks.
I have a Noctua NH-U12P SE2 and it works for me.
http://us.ncix.com/products/?sku=42819&vpn=NH-U12P%20SE2&manufacture=Noctua
I have it mounted with their 90 degree rotation kit that you have to contact Noctua for, they send the rotation kit free of charge if you just email them a copy of your receipt with your motherboard and Noctua heat sink.
rotation kit- http://www.noctua.at/main.php?show=productview&products_id=36

If you want a little better Noctua cooler try
Noctua NH-U14S
http://us.ncix.com/products/?sku=82802&vpn=NH-U14S&manufacture=Noctua
or their beastly cooler-its really freakin heavy-Noctua NH-D14
http://us.ncix.com/products/?sku=47090&vpn=NH-D14&manufacture=Noctua

If you wanna goes nuts overclocking and do it with water, I would suggest you consider building your own water cooling loop. And consider another case like the Corsiar carbide Air 540 or Corsair 900D

Good choice on the Samsung SSD.
For the power supply stick to Corsair or Seasonic. Just as the other guy said.

I assume you're familiar with the frame pacing problem that has plagued the 7990 and Crossfire setups. This problem was only partially fixed in the recent 13.8 beta drivers, but the problem persists for DirectX 9 games (Skyrim, COD, etc.) and multiple monitors. If you are thinking of adding another monitor, the 7990 will be a waste of money until there is a fix for Crossfire and Eyefinity.


Another issue is the heat and noise generated by the 7990. You need to make sure you have a full ATX case with plenty of ventilation. The 7990's fans blow air directly upward and into the case with almost none going outside through the I/O port. This will significantly heat up the interior of the case and put stress on your other components. AMD recommends the Cooler Master HAF X.

Just arming you with important information as installing a 7990 does require some planning in order for it to work as advertised. Note, you will get the coil whine noise noted in the recording on this page:
http://www.tomshardware.com/reviews/radeon-hd-7990-review-benchmark,3486-15.html

Quote:
"When it launched, a generous eight-game bundle had me on the fence about the 7990’s prospects. But after spending time evaluating its thermals and acoustics (to say nothing about its crashes and performance hiccups in CrossFire, which could become a story unto itself), I can’t think of one reason to recommend 7990 to a friend. And, at the end of the day, that’s what this job is all about."

Hi, thanks for your time and your attention man, well, I've decided to changed the case as @17 seconds said to the Cooler Master HAF X, the Carbide Air 540 hasn't got enough slots as I need, so... and as I decided to change the case, I changed the Cooler, now I'm thinking about th rx360 mm push/pull radiators, which I think it will fit, but not sure about it...
I will definitely by the 850 w professional Corsair PSU.
Any other advice?
Thank you very much!!

Hey, thank you very much for your answer :)

I wasn't really familiar with that info... and the quote was like a punch hahaha, so I've been looking for other graphic cards and found two which I think will run without problem at 2560x1440 ultra settings in any game and with 2 or 3 monitors also, so I found:

First of all, the 6gb Sapphire toxic hd 7970 Ghz edition, which I think it will fit my Asus Crosshair-V Formula-Z, even crossfiring it with another 6gb Sapphire toxic hd 7970 Ghz edition, don't you think so? (http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&lid=1&pid=1483). I know the sound is high, and also the temp. (http://www.tomshardware.com/reviews/toxic-hd-7970-eyefinity-6gb,3264-6.html), but I think I'll be able to control it with a good cooling system.

In the other hand, ther is the 3gb Gigabyte HD 7970 Ghz edition (http://es.gigabyte.com/products/page/vga/gv-r797to-3gd), which I think it will work really good as well, even with crossfire :)

So what do you think? What should I do?

P.D: I changed my case to the HAF X, and I am going to use the rx360mm radiator with puss/pull, do you think it will fit? Because there is people that say it will and people that say it won't... (http://www.overclock.net/t/910545/i7-950-haf-x-rx360-rasa-water-cooling-log-lots-of-pics)

Thanks for your time and attention mate!

Okay, those are much better options. You could almost flip a coin between the Sapphire and Gigabyte cards. 6GB will be useless even in Eyefinity, but if the price is right, the Toxic is a great card with custom components and a cool overclocking mode.

The only issue I can see, since its still Crossfire you're going to have frame pacing problems with DirectX 9 and OpenGL games and multi-monitor resolutions... until AMD fixes the drivers, which they have promised to do. The frame pacing problem, in brief, is basically Crossfire setups will not deliver smooth performance despite the fact that they are showing high FPS numbers. Generally, under those circumstances, Crossfire performance is similar to only running a single card (check reviews that use FCAT testing).

You will also get games that lack proper game profiles and will not run with both GPUs enabled. In TechPowerUp's review of the 7990, they had the following comment regarding games that didn't work in Crossfire:

"we've also seen many games that do not scale well, and they make up a significant portion of our tests. Out of eighteen titles, five did not scale, or worse, showed negative scaling. These are not small titles, but big AAA games: Assassin's Creed 3, Batman: Arkham City, F1 2012, StarCraft II, Skyrim, and World of Warcraft."
http://www.techpowerup.com/reviews/AMD/HD_7990/31.html

If you set your expectations accordingly and tweak everything out, you can get the most out of your setup and minimize some of these problems.

If you feel that bezels will ruin your multi monitor experience you may consider instead getting a companion monitor setup. One large 1440p screen and one really tiny ~9" screen off to the side. Games can still be run traditionally on the single large screen but Windows can remain on the companion screen.

Hey, never heard about that setup.. how would that work? just buying a 9" monitor and connecting it with the HDMI to the card? If it's like that, that's awesome!! And to make windows run on the little I would just have to go to the card settings right?

Wow man, thank you very much for your time and your advices!!

Hey brother got a question for you...a friend of mine has this ASUS board with 2 HD 7990's in QuadFire. This is what I want to do for my build due to the fact that I will be running 3 1080p 24" monitors in eyefinity and I want the PC to be future proof...do you think I'll be alright? Anyone can answer.

Radeon HD 7990 In CrossFire: The Red Wedding Of Graphics
http://www.tomshardware.com/reviews/radeon-hd-7990-crossfire-overheat,3539.html



"As AMD has already publicly stated when the frame pacing feature was first introduced with Catalyst 13.8 beta, it does not address resolutions above 2560x1600. At the same time, AMD has also committed to addressing these cases in a future update. Details of the rollout for this solution will become very evident, and made public in the very near future."
http://www.pcper.com/reviews/Graphics-Cards/Frame-Rating-Eyefinity-vs-Surround-Single-and-Multi-GPU-Configurations/Video-

"And of course, this fix, that comes with a combination of a new driver and a completely new hardware level implementation of CrossFire, doesn't help users of the R9 280X, 270X or even the Radeon HD 7000 series cards that are already out in the wild. We are still waiting on the promised answer from AMD for those consumers that bought into the idea of CrossFire as well as multi-display gaming."

Get the new R9 290X instead and 2 way crossfire it. That is what I would do.
