I'm using the 12.4 beta's, I've no idea which are best, I just chucked the beta's on because they were the newest and left it at that.
If you were to change I'd say uninstall the 12.3's completely and then reboot, and install the 12.4 betas afresh.
That 7870 is looking seriously tasty, hows the fan noise on it as it seems to run about 10C warmer than the 50's?

FXAA is much faster, gives a much smaller performance hit and AA everything, gives the equiv of about 4x traditional AA, but some people find it a bit blurry (it gives a softer image).
PPAA is the same thing it's just what it's called in BF3, set it to HIGH.
MSAA is the traditional AA method that gives a sharper image, but a much much larger performance hit and doesn't AA certain effects, you need a lot of card grunt to be able to use it in BF3.
Personally I think FXAA/PPAA looks just as good as MSAA in BF3, and runs considerably faster.

we need some competition from nvidia to lower these 7850's prices

670Ti/670 not due 'til May, and 660 not due until 'Summer'... so that might be a while off yet.
im loving it think ill chuck another one in around august time 
I second that.
From what I can see the only benefit of these cards it that they are quiet, cool and use little juice from you're wall socket. But for pure brute power the 7870 is close to a 570, which can be had for a lot less. But they are a bit short of vram, but then an evga 2.5gb can be had for around the same price.
I just get the feeling that the green cards will be a fair bit better, when they finally join the party.
Would you not agree making a game look super sharp causes it to look unnatural? Like someone bumped up the sharpen filter. I think FXAA is really nice. I honestly don't find it all that soft and the little jaggies you do see, and they're minimal, you only really see it if you compare screenshots. Once you walk/run around everything is solid lines.

I am not too impressed with the 78xx cards. The 7850 needs clocking up significantly to match a gtx 570 , which itself can be clocked out of the 7850's sight. It has been said that a 7870 almost matches a 7950 in bf3. Well thats because a 7870 is at 1000mhz and the 7950 is at 800mhz. If i was buying the 7870 i would save a bit more for a 7950 which can be had for 313 quid.

The difference is the 7850 is cheaper than the 570, uses half the power, runs about 25C cooler under load, and makes almost no noise, while matching/beating its performance. Yes they like to be OC'd, but then again this is OCUK, where the entire point is to take a cheaper card and make it better than a more expensive one, which the 7850 does handily, while having all the other benefits listed above. Looking around the web I've not seen a 7850 that can't do 1050 core on stock volts, it seems that AMD gimped the card deliberately to fit within a TDP, and in actual fact the cores can go much much higher.
As for your comments on the 7870... yes the 7870 is clocked higher... but it also has far less shaders... swings and roundabouts... one is high clocked/low shader the other is low clocked/high shaders, doesn't make any difference to performance in the long run! Both offer up great FPS in games.
Yeah you can get a 7950 for £313, you can also get a 7870 for £255... that's a £58 (18.5%) saving for very similar performance once OC'd. Not really something to be sniffed at.
Personally having used both a 480 a 570 and a 7850 I don't know why anyone would choose the former two now. Yes they are slightly faster, but at the cost of much higher fan noise, much more power draw, and much higher system temps. For me a couple of extra FPS isn't worth all the negatives the other cards bring. But then that's just my opinion, if you dont' care about any of that then knock yourself out on your 480/570 setups, i'll be busy enjoying total silence while I play

You can get an HD7870 for around £250.
Maybe its not as bad as i thought then, i appreciate silence on gpus. I still dont see it matching a 570 in games though, unless you are comparing a overclocked 7850 against a stock 570. If the 7850's unlock that would be a huge plus, anyone tried it yet?

Dont know where you get this from, from what i can see 7870 has more shaders than 7850 and higher clock speed. 7850 probably can overclock by a higher percentage though. I know about the point of overclocking thanks, my gtx 570 is at 900mhz.

OC'd the 7850 thrashes a stock 570, it matches a 580 for the most part (Bat AA and BF3 being the exceptions as they love nVidia architecture), both OC'd they are probably about on par with each other.
A 7870 OC'd destroys a 570 stock or OC'd.

Exactly.
from that link i see a 7850 overclocked pretty much matching a stock 580. But a 570 at 900mhz like mine would at least match the overclocked 7850. It represents a 21% overclock on the stock 570. However if some 7850 users on here can tell me they have voltage control and can hit 1150-1200 mhz on the core i will be impressed. Im only interested in overclocked vs overclocked performance really.

As I said a 7850OC will be around the same speed as a 570OC, not disputing that. However the 7850 has many more benefits that make it a better buy than a 570. IMHO.
Cooler, quieter, less power draw, and more memory. While performing pretty much the same.
Kind of makes the 570 defunct now, the 7850 is just a better buy all round.
