turning of FXAA will give you a big boost in frames ... if you *really* want to have some degree of anti aliasing, POSTAA is generally fine, FXAA takes 20x more work, for what I would call a 2% improvement .... and besides, when frames are whizzing by at their maximum, you don't really have the time to see each one individually, and recalculating it per frame, becomes, wasteful ...
you might want to try turning vsync on, generally I'm against vsync in principal, I see that the native for the screen is 75 hz, and enabling it might actually help you get there, without downgrading FXAA ... if you really don't care about the refresh rate that much, you might try locking it into 60 hz, and putting vsync on, it would probably give you a more 'consistent' frame rate overall ... with the drops to 40 odd fps still being 2/3s of 60, instead of feeling as though you've dropped 50% performance ...
the memory controller within the cpu is only rated for 1866 MHz ... so, you could try pushing on that, but your most likely to just find instability, and I don't think you'll 'need' to ...
your video card is basically the same as mine, although I did not get a super clocked edition, and I'm pretty sure it had a slightly different fan strapped on, I yanked that off and dumped on a 'Corsair HG10 970', and I can tell you that at 1080p, your never really 'pushing' the card to its limits (you need 4x more resolution), so when you experience slow downs, its probably not related to the GPU in any way, and its probably the CPU feeding everything becoming bogged down ...
and if your problem is CPU power, that its probably relating to the least optimized part of the game, the battlegrid, and the only thing you can really do right now to improve the situation, is turn off the team information, which I think by default is the -> ; <- key ... well, you could turn off the whole HUD, but just the team information is probably far enough ...
supposedly there is a bit of overclocking headroom on that CPU from its stock clocks ... and that *would* help you, but it can be like swimming in the ocean, it looks fine, until your being dragged out to sea ... the suggested realistic maximum, is 4.6 ghz ... you mention water cooling, I assume a reasonable AIO setup, which suggests to me that you probably have some room to squeeze there, think about this path last .... as it gets complex, and right off the bat I'm not familiar with which process is used on that processor or how far out of tolerance it needs to be pushed to become achievable but its essentially a black edition cpu, and the multiplier should be unlocked, depending on how the bios feels like intepretting things ... as a general rule of thumb, on a water block, you should probably be able to achieve the turbo frequency on all cores, with little extra stress placed onto the components, if you do any overclocking on the FSB, the RAM speed gets pushed upwards as well, and that gets much trickier ...
but you could probably disable turbo core, leave on cool and quiet, and adjust the multiplier to be 4.2 ghz, without changing the voltage at all ... before you do this though, make sure you know how to reset the bios to default in case it doesn't like it ... you haven't specified the motherboard, so theres a few random factors in there .... but if its good like that, then you've probably just gained 10% on the single thread performance ... and sitting at the high edge of nominal tolerance ...
