Upgrading to dual video card setup

post #1 of 3
Thread Starter 
I want to upgrade my signature rig to dual video cards and not sure what I should get. Right now I have a Saphire 6870 and it works great almost all the time outputing to a 42" lcd TV. I was thinking I might get another of the same card but I don't know what kind of performance gain that would get me. I also want the ability to output to a second smaller monitor. So i guess what I want to know is should I get another 6870 or should I buy a 6900 series and and a second card later? I am partial to AMD/ATI cards and I want it to output directly to HDMI without any adapters. If anyone has any suggestions I'd love to hear them. Thanks.

I forgot to ask about the power supply I plan on upgrading that at some point so that's not an issue.

750 should be enough. It more depends on how much amps you have a the 12v rail. Dual 6870's should be more then enough for your liking. Should net almost 100% performance gain. Best to look at some online benchmarks to see what kind of ball park you should get. Head over to the PSU section to read up on power supplies and then hit the interwebs looking at benchies for the 6870 crossfire.

If you already have one 6870 then definitely go with another. 6870 s scale very well and two in crossfire will last you at least another two years if not longer.
