i am looking for an amd graphics card an i came across this, http://www.amazon.com/Sapphire-DisplayPort-PCI-Express-Graphics-21196-00-20G/dp/B00BXVFM3K/ref=sr_1_4?s=electronics&ie=UTF8&qid=1372553632&sr=1-4&keywords=amd+7950

 

 

i am thinking about buying 3 of them because my motherboard supports 3 way and i they fit the price.

 

should i buy 3 or 2 or just one.

After two way configs, latency increases to the point where 3/4 way configs are pointless. Also, if a game happens not to support multi-GPU configs very well, the performance may stay the same, or decrease.

Performance wont decrease only the way it scales will decrease, to the point of buying it almost pointless.

In Euro Truck Simulator 2 when using SLI, my FPS is very low. When setting a profile for Single GPU mode, the FPS goes back up.

I would recommend getting 2 7970s, since they're so cheap right now.

with the reference coolers you would pretty much need to water cool them as those blower coolers don't work well when there are loads of them in a small space

I will be running two sapphire 7950's but a single 7970 would be perfect. if you want to splurge, why not get a second 7970.

if you thought about buying 3 $300 cards, why not just get a 7990? a single card solution is always better.
