flasher33 :
I have a MSI NVIDIA GeForce GTX 680 lightning and thinking of getting one more.
I couldn't find it on amazon at a reasonable price.
I found the MSI NVIDIA GeForce GTX 680 Power Edition and thought of getting that instead.
will it work in SLI ?
Yes it will work perfectly.Only thing is that you have to underclock your lightning,or overclock the new PE so that both of them work on same frequency.
Your lightning has 1110Mhz core clock,while the PE has 1019Mhz as I remember.But with afterburner is easy even for first timer to do the required OC.
Cheers
