Hi everyone im about to purchase either 2 6970s or a 6990 to last me a while and ive pretty much leaned towards the 2x6970s reason being noise/heat and im not going to watercool.

Anyways what i wanted to know is if i xfire the 2x6970s what is the best brand ones to buy and will i be able to fit the 2 cards and my fatality pro sound card in alltogether???

My specs are HAF-X942 case and R3E Mobo atm i have alot of room to spare but just wanna make sure i can fit it all in and not waste money any info would be great thanks.

crossfiring the 6970 will generate more heat and noise as there is two times the fans as normal and gigabyte is generally the best brand to buy as they usually have triple fans for silent cooling. And your case will be able to fit the cards no problem.
 

the heat and noise thins is true. Gigabyte, Sapphire, MSI are all best brands as long as they are non-reference designed cards.
non-ref designed cards have better cooling, lower noise which give more headroom for overclocking
Gigabyte HD 6970

MSI Lightening HD 6970 (overclocked already to 940 MHz)

check the reviews & feedback of each card before buying
 

+1 on the lightning twin frozr from msi.

Thankaps for the help guys and i think im most likely going to go with the gigabyte ones seeing as the lightnings are alot more expensive.One last question though because my mobo is asus will the gigabyte cards function fine ? like different brands dont matter at all? and do those cards perform well??? any benchmark links would be great to thanks again.

Last thing to some ppl have told me about something called microstutter when xfiring? any info on that to would be great seeing as this is my 1st time xfiring and dont wanna *** it up somehow lol thanks.
 
for the gigabyte GPUs thing my answer is ...lol :D
HD 6970 crossfire performs better than HD 6990 in many cases, and yea they are great GPUs.
Microstuttering has been explained recently by Tomshardware and it happens with both nVidia and AMD, HD 6850s/70s in CF was doing creepy unlike the HD 69xx... Unless you go with a 3-way CF/SLI which sounds ridiculous

what is your PSU Model to confirm you're good to go ?

EDIT: review for HD 6970s crossfire

http://www.guru3d.com/article/enermax-revolution-850w-review-test/ and also will i notice this micro stuttering thing or is it nothing to worry about ? and you did say gigabyte cards were good right? lol @ internet sarcasm.Also i was wondering if i would be able to fit in 2 of the asus DCII cards and my sound card seeing as i heard its a really good card.
 

they are all really good brands and nothing to worry about, but the Asus DCII will take 6 slots wich will be a huge problem for sure, what's your mobo ?
