So im building a new PC and i have triple monitor display at a res. of 3840x1024

I really like the idea of having dual Gigabyte HD 7950s in my system, but i heard so much problems with micro-stuttering. Is there any way to reduce this or completely get rid of it?
Or do the newer drivers have fixes with this?

I also saw the Evga 3Gb GTX 660, but i allways had Radeon and would like to continue since ihave good experience.


What Do you think?

3x1280x1024 is still less pixel than 2560x1600. I think you should be fine with a single HD7970. It'll save you some money instead of getting 2 7950s and the performance will be more consistent.

I just added a 2nd 7950 for crossfire in my rig. So far I love it, I havent noticed any issues with micro-stutter although I've only been running them less than a week. What the previous poster was saying about the 7970 is that for your setup, while 2 7950's will give you more power, since you arent running that high of a resolution, you could get away with a single card rather than two, in which case a single 7970 might be a better choice for you than going with 2 cards. Before getting my 2nd 7950 I could game at 5760x1080 comfortably, I only added my 2nd card so i could crank the eye candy up to full in games, but even without it things were more than playable.

Both my 7950's are by Sapphire. One of them is the boost edition, one of them is the OC edition. The site I used no longer carries the OC edition I bought (bought April 12), but heres a link to the boost edition. Physically the cards are identical, they just run a different bios.

Thanks, but im getting dual XFX 7950 Double Dissipation Black Edition cards because of their high clock and memory speed (MC: 5500mhz and CC: 900)

Ok, CC 900mhz isnt that much but good enough for me xD
Thanks, i was thinking for duals sapphires too, but the XFX are just a bit cheaper :D 

Btw, is this PSU good enough for my dual GPUs (does it have te right connectors)? In the description it says 4x 6-pin connectors. Thats good right?

PSU that you showed is more than enough. As far as Sapphire vs XFX, the only reason I got the Sapphires where that they were cheaper so I dont blame you if you can get the XFX cheaper than the Sapphires where your at then I would definitely go with them.

Yeah I know what you mean. Originally the 7950 was about $470 if I recall. I waited for a price drop and got my first one for $400 about 8 months ago. I got my second card less than two weeks ago for $300. Its just the nature of computer prices, you have to pay to stay on the cutting edge.

So im curios just about 1 more thing. This is my first Crossfire PC, so... How do i connect my screens? Do i connect them all to 1 gpu or 1 on the bottom, and one on the upper gpu? Or all on 1 card? Haha sorry if its a stupid question!

Hi - plenty of power for your 2 gpu's, and xtra headroom as well.

Thanks to all of you (@toyftw, @AdioKIP, @EzioAs). I have just ordered my new PC 2 hours ago. It should come around Saturday. So here are the other specs if you wanna know:

Asrock X79 Extreme4
Intel Core i7 3820 3.6GHz
Grand Kama Cross Rev. B (CPU Cooler)
Dual XFX 7950s Black Edition Double Dissipation
12Gb of RAM (from my previous PC) 1600MHz
Western Digital WD10EZEX "Caviar Blue 1TB 7,200RPM
Corsair Enthusiast TX 850W
Cooler Master HAF 922

What do you think of my setup? This is the replacement for my 5-year old PC that died. The mobo doesnt even recognize the ethernet cable (although weve tried 3 different xD)

Why X79?

Because X79 is the newest and best CPU's. The reviews from video editors and others are amazing, while it's also perfect for gaming (although a i5 rig would be good for gaming) i nee this PC for multi-tasking and video/picture editing, that's where the Hyperthreading comes along well!

I had the Intel i7 920 in my previous PC, it was good, but it was missing some serious power. That's why i got the X79, also because it's what the army uses...

:D

The 3820 isn't any better than the 3770K. Why not just get a 6-core 3930K if you were going to go X79?

Yes, but the i7-3820 by itself doesn't have much, if any, advantage over a 3770K even though they cost almost the same. However, X79 motherboards are generally more expensive than most Z77 motherboards. Unless, you need more than 32GB RAM and the PCIe configuration, I don't see any benefit you'd get with an i7-3820+X79 board over i7-3770K+Z77 board.

Yeah... I just like x79 but the mobos are expensive... Anyway about my monitors... Do you know which card i should connect them to? All on one or how? I need to know this because i might be getting this tommorow or Saturday...

Thanks
