It's only really relevant to people buying now, HOWEVER you could sell your GTX680s and get 7950s, make a profit and have more performance.
So in that regard, I think it's relevant for people to say, though I know it's very unlikely that you'd consider selling your 680s anyway.
I seriously considered this for a spell and I would have gone for 2*7970s instead (purely for the benching). After common sense kicked in, I realised I have 2 of the best 680's available and games over 1 or 3 screens run fantastic. I generally play games with no fps counters running or even any overclocking (I forget to start AB up). They run smooth enough for my liking with most of the games on ultra detail.
I also love pushing my hardware as far as it can go and I do hold the fastest SLI 680's in the 3DMark11 thread
And I don't tend to game so much in 3D as I used to but I still realy enjoy when I do, so this keeps me Nvidia bound for now.
Gregster knows he can get better performance from a pair of 7950s and has accepted it. It doesn't really matter to him now does it? He's had superior performance for months before 12.11.
As I said while testing the difference between the two can be summarised between playing at maximum settings and not. Quite impressive for a £240 card no?
The gap for gregster is smaller as he has better 680s but it will still be a big gap as my own 680s were pretty golden.
Nice one. Mine can do 1200 but I don't really need the extra for a single screen so run at 1100 and 1500. My card gets a little cranky above 1550.
I have known since day one and possibly chose to ignore the fact that the lower memory bus on the 680's would be a deciding factor when playing across 3 screens. I expected 2 * 7970's to beat me but wasn't expecting 2 * 7950's to beat me if I am honest...That kinda hurt a little
I have no intention of swapping out 'The Precious' though, as they can clock much higher than other 680's I have seen and I am not representative of normal 680's IMO.
When did you get the Lightnings?
lol bro, I knew you would have something to come back with

. My Original 680 from EVGA was the first released batch and was pretty special. It clocked up very nicely and held the fastest 680 in the Heaven thread for a long time. It was only after seeing OptimaLNRG's score, I decided to get a lightning for SLI and 3 screens and then seeing how well one clocked, I gambled on getting a cherry second (which worked). My second isn't as fast as my first but it isn't far off.
Banter aside though, I still go back to my statement early in the thread and say without a fps monitor running, Joe Bloggs would have no idea what GPU's were in which machine when gaming.
Edit:
Rroff hits on a point which is valid, The latest Beta drivers are not 'performance drivers', they are broken betas and give less performance in BF3 (I checked these against 304.79 which seems to give the most performance in BF3 in SLI). Hopefully they can pull something out the bag and not sure what is left in the tank to do this.
