Things are pretty decent, however I feel like I've been getting ever so slight a touch of lag...

The best example, Battlefield 3, 5760 x 1200, auto settings, I'm getting 15 to 50 FPS, averaging just over 30, but then the sudden drops to below 20 fps are killing it for me... I spoke to my AMD Guru who tells me I need to change out to an AMD motherboard and ditch Sandy Bridge LOL Bah to that, but I am thinking perhaps the NF200 chip is sucking...

So I threw hardware at the problem and got a third EAH6970 for tri-fire, sure enough the max FPS improved, but I'm still getting the sudden drops in FPS. Tri-fire seeing 15-70+ I disabled crossfirex, using one card and Eyefinity, interestingly I'd get less FPS but I wouldn't drop down to 15 fps. I'd see 20-30 the game was more stable (but FPS to low). As a test I start my rig using MSCONFIG and disabled everything but Microsoft stuff, not much difference in game play, but a slight performance increase.

All things being equal I'm starting to suspect the motherboard has issues. What the issues are, who knows? BIOS? Hardware?, NF200? Anyone think I just need tweaking of some sort?
1. You don't need to change the motherboard or any of your hardware. Whoever told you that you needed to do that is.. well.. this forum will banana dance men out the words required

2. The NF200 chip does have additional latency costs, but nothing that should effect FPS too badly.

The more than likely cause for your FPS drops are either;

A: Poor coding in the game, probably fixable with a patch if FPS dips like you have are a common problem
B: Poor AMD drivers / profiles. In this case you just have to play the waiting game to see if AMD fixes it.
C: Of course, make sure all your other drivers are bang up to date.
D: Try a HDD defrag with a good defrag utility like diskeeper.
