3x 7950 or 2x 7970

post #1 of 39
Thread Starter 
Intend to be running a triple monitor setup where I will be multiboxing EVE (10+ clients), want to play Crysis 3, Skyrim (maybe modded), Bioshock, Farcry 3, and Borderlands 2. They are 3x 24" LEDs and will just be running 1080p for the moment although I would like the ability to do 1440p later on. But will work with what I have for now.

I guess I have been mildly convinced that ATI is the way to go for the video card for now.

Was thinking 3x 7950s or 2x 7970s would be a good fit for my set up.

I will be running:
i7 3930k
ASUS Rampage IV Extreme
32gb of RAM

and other basic stuff, will decide on PSU once I decide on how many cards and what cards I will be getting. As well as my water cooling solution.

As far as the cards go I have been leaning towards the 7970s the last couple of days. While they might be expensive they same like they will perform well.

2 x 7970, for one sole reason... 6gb VRAM which is essential for 3 monitors, Dont get the 7990 as it is 6gb shared so its 3gb usable

He made no mention of a 7990. Also 2X 7970 does not give you 6gb of ram unless you buy 6gb 7970's, VRAM is still shared even in crossfire.

3x 7950 will definitely give you better performance over 2x 7970. OC'd 7950's are already close to 7970's as it is.

The 2x7970's 3GB doesn't add up mate

3x 7950 obviously has more power... no microstutter either. Just really hot.

Perhaps some of this CLC action?

3x 7950, if you got room. Much faster and alot less microstuttering with 3 and 4 cards on AMD compared to just 2.

I sold my 7970 CF setup due to mad stuttering (didnt have room for more cards)

Microstuttering happens with 3 cards as well with two cards.
What one want is enough fps 60+ and make sure the minfps isnt going down much.
syncing issues will always happens with multigpu set up, Nvidia as well for amd.

3x7950 allows more horsepower which for the price/performance ratio is the better deal. You get 3 7950 for the price of 2x7970 here.
adjust settings until one gets the best performance and the iq one want.

AMD 7xxx series has significantly worse micro-stutter than the Nvidia 7xx series. Nvidia have very little.

3 7950s would perform better.
