First of all, what is the difference between this:

and this:

Aside from the CO in the name I cannot see any difference.


Secondly, I read in some review on newegg.com that even if your mobo isn't SLI, you can run a mock-SLI if you have both a PCIe and PCI card plugged in. Is this true?

EDIT: Okay, I lied.. one more question. Is SATA3 backwards compatible with a SATA 1.5 mobo?

Thanks

I just went thru the entire tech sheet on newegg.com and I can't find a difference either... but the first one is 5$ cheaper so I don't think that the CO is a big thing performance wise... Might just be some kind of connector or something...

I don't think it's all that important.

"CO" is the designation for "Copper Heatsink".


Except for a few older via chipsets, yes.


Never heard of that one.

Forget what I said go with the more expensive one. I think it's worth the 5 bucks for the copper heatsink espicially if you are a big gamer and all...
