Hello,

I feel like I've always had problems with my PC, like its not performing like it should. It gets very laggy with some games and not even highest settings. Call of Duty Ghosts has to be scaled down to mid level settings, very frustrating. Some games will work better, like Assassins Creed 4. But then in game it starts raining, and the computer slows down to 5FPS. Re-did my graphics cards' drivers several times with no luck.

I thought it was my Graphics cards, but stress tests come back okay. Memory tests come back okay.

Yet another strange thing is that by default the motherboard wont recognize my memory as being 1600 speed, and I have to manually change it in BIOS (I have the latest bios version, by the way).

Specs:
Asus Sabertooth P67
Intel i7 2600K
Corsair Vengeance 16GB (4x4) 1600mhz
2x EVGA GeForce GTX 560 Ti 1GB GDDR5
Samsung 830 Series SSD 128GB
WD 1TB Caviar Blue

This system is in an NZXT case with maxed out fans, a Coolermaster hyper 212 Plus on the CPU. Could it be that the memory is not compatible? Perhaps my system is overheating?

Some games do not utilize or scale very poorly with SLI. That is probably the reason one. And other games do support SLI or scale fairly well with them, which is why you're getting good performance on other games. These are problems that SLI can cause, which is why people typically don't bother with it.
Your best bet is trying to sell/trade the GTX 560 ti and get a better, newer card like the R9-270 or GTX 760 or better.

-try updating your graphics driver and all your drivers in general
-scan your computer for viruses and malware
-defragment your Hard Drive
-run Ccleaner (http://www.piriform.com/ccleaner)
-make sure your ingame resolution matches your screen resolution

still no benifits? try fomating your pc and start with a fresh install (back-up imporant file's)

I did all of this, still no luck :[. It took me most of my Sunday, too haha.
Is it possible that something is incompatible that I'm not aware of? Still possible overheating?
I thought it made sense that it was the graphics cards, but the stress tests worked fine.
Perhaps the memory is still suspect?
