How does one OC cards separately btw?
sweet thanks for the info - I'll definitely re-install the drivers, to be sure smile.gif!

OC'ing both or leaving both at stock is recommended.
Boost 2.0 will clock the cards (at stock) depending on their ASIC values which predetermines the clocks/volts for the boost function.

Different ASIC cards will yield different clocks at the same stock volts (1.162v) which is completely fine.
(One of my cards boosts to 996MHz while the other reaches 1058MHz under the same volts if left on their own which showed no issues whatsoever during gaming).

You can use AB to OC each card individually but it's just unnecessary:

ah my point is:
Say I reach 1200mhz on one, but the other doesn't get to 1100.
Thus I would have to clock them both at the lowest OC profile.

After playing on BF4 yesterday (saw some artefacts) - so dropped my mem clock a bit.
I THINK this is my stable on my MSI 680:



Sweet about AB - I downloaded EVGA precision, but didn't like it over AB.

Would having two gpus clocked at different speeds cause more of this though? Considering the delivery of the bits would but off by quite a bit (no pun intended), these are just some things I have noticed when I was deal with my gtx 560's one is a 1gb and the other is a 2gb and sometimes I would forget to set afterburner timing and would see noticeable issues of this caliber.

Oh definitely - but depends on the resolution.
2x GTX680s running 1440p will struggle to tear my 96z monitor.

However 1x GTX680, l;et alone 2x GTX680 will EASILY cause screen tearing on my 60z 1080P monitor smile.gif

Tearing occurs when the MONITOR can't keep up with the GPUs - ie your monitor is your visual bottlneck.
I decided to say to myself:
"IF I can get a second GTX680 OR sell my current one, then I'll buy this new 1440p monitor".
I ended up getting a great deal on a GTX680 - so I then ordered the monitor.

2x GTX680s on my current monitor would be silly.

For the first time ever, I can now say I got no real bottleneck in my system smile.gif!

And that sir is a beautiful thing.
