As for the LE, I think it was disabled because of x16/x4 PCI-E lanes. Though I could be wrong.
Second point makes sense. Major cost cutting in this board.

Anyhow, I would use Afterburner because it allows voltage control, which will increase your maximum overclock. To test, get OCCT and do the GPU test for an hour or so.

while this may be true, it's an easy way for asus and other companies to force users into buying more expensive motherboards to get higher end features.

You are incorrect because a nVidia GPU will NOT work in a x4 slot out of the box and you are thinking of comparing x16 to x8 and its a maybe 5-10FPS drop in real world games what you would see using an nVidia GPU. Now I think you CAN run Crossfire in a x4 slot but im not 100% sure

You couldn't be any more incorrect. I've ran plenty of nvidia cards in x4 slots.

Though crossfire will work with x4. I've even ran them in x1 slots for folding in the past.

I've seen places claiming I can run SLI and places saying I can't..so is replacing your motherboard as simple as removing components/sliding it out or would i have to get it professionally done?

It's probably the most difficult single thing to replace in your PC, mainly because everything is connected to it. The only other thing that's close is the power supply.

This being said, it's still not all that hard to do. Just pay attention to where everything is plugged into it currently, and then plug things back in the same way on the new board. They're pretty 'standardized' in terms of layout, and you really can't plug anything in 'wrong' as everything is specialized connectors that can only be plugged in in one place.

The *only* tricky thing is plugging the case connectors back into the board (power switch, etc) correctly. This will often require consulting the manual, and good eyesight really helps because the connectors are TINY. Although if you just upgrade to the Pro, the header for the case connectors is probably identical to the one on the LE, so that will make it easier.

Also don't forget to replace the rear I/O panel when you switch boards (the aluminum piece that surround like the USB jacks and such on the back of your PC). New mobo's come with them, you just have to pop out the old one and pop in the new before you place the new mobo into the case.

I have a pretty good feeling though that a single 560ti is going to handle BF3 pretty damn decently. You may not be able to pull off really high AA levels, but you should probably be able to max it other than AA would be my guess.

As others mentioned, AB is preferable to Precision just because it has voltage control, whereas Precision doesn't. Although since you're really new to OC'ing it's maybe best to just leave the voltage at stock for a while until you learn the ins and outs of OC'ing. In which case, Precision works just as good. It's really almost the exact same program as AB, just w/a different skin and missing a few features.

I'm not going to re-write the book on 'how to OC a Fermi card', because there's TONS of them around the webz. Google is your friend on this one

Personally I use loops of the Heaven, 3dMark11, and Crysis benchmarks to test stability. I've found that if all three of those run w/o problems, the OC is stable.

Well, the reason for the worry is that I can't do any AA at all, really. I have to keep games like SCII and Just Cause 2 using no AA to stay at 60 fps...but it really sounds like I should be able to do better. My card isn't EVGA superclocked like my friend's card is..and he can do high AA levels no problem.

The small increments of clock speed differences in vanilla cards and SC or SSC cards isn't enough to make a difference in whether or not you can use AA, perhaps he us playing a lower resolution than you, or has a few things turned down from the maximum.

So overclocking it myself would probably push it beyond the superclock level. Is there any particular reason EVGA chooses to use those speeds or can I go crazy with it?

I believe they choose those speeds because they're guaranteed stable. You can push it as far as stability and temps will allow.
