Bridging two 6670's - good idea?

[Jugeezy]

Title says all. I'm going to bridge them, and I was wondering how good the performance would be.

Also, my PSU box says SLI ready, so I am also wondering if that is relevant or not (my first build, excuse my badness )

EDIT: They are the Sapphire Radeon HD 6670 1Gb 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Video Card (11192-22-20G)

That would be a pretty neat trick if you could do it. However, the Radeon HD 6670 is not CrossfireX compatible so, if you install a second one, it won't accomplish anything useful. Please see the following CrossfireX compatibility chart from AMD for more info: http://sites.amd.com/PublishingImages/Public/Graphic_Illustrations/WebBannerJPEG/AMD_CrossfireX_Chart_1618W.jpg

Welp, that just goes to show how much of a noob I am . Thanks!

I thought 6670's were able to crossfire without a crossfire bridge? Could be wrong? but remember reading something about it.

Regardless, it still wouldn't be worth it as for the same price you could get something far superior and would guess you would have a severe amount of micro stuttering issues

You can Crossfire 6670's. That chart doesn't cover all AMD cards. You just don't need the Crossfire bridge.

Yes you can but only with an A8-3850 APU and 1 dedicated 6670 video card.

Did you not read the link I posted? The CPU they were using was an i5-2500K. You can Crossfire two 6670's.

Yes you can crossfire 2 6670s, it does not require any sort of crossfire bridge. It is all done in the software. Though I am pretty sure that this gives worse performance then if they originally included a crossfire bridge on the actual card. Though I have nothing to back up that little piece of info other than my own insight. (why add it if it offers no performance gain, right?)
