My 285GTX and my HD7770 ?

[Shadowmeph]

I have been finalizing the changing cases and such today and on the first boot up I ran some tests and n oticed for the first time the difference between my 285 2gb GTX and my HD7770 , ( of course this happens after I spent all of yesterday and lastnight setting up my watercooling getting all of the air bubbles out on my main PC). I the openhardware monitor and the clock speed of ( what I thought of as Powerful) 2gb 285GTX is 666MHz, where as the HD7770 is 1025MHz . If I where to switch out this Nvid card for the HD7770 will I notice any difference performance wise?
the 285 has a bus width of 512bit, vs the HD7770 which has 128bit, the Bandwidth of the 285 is 148.6 GB/s where as the HD7770 has 72.0GB/s. the 285 has 240Unified shaders but the HD7770 has 640 Unified shaders.
Now I have only played gamings with the HD7770 installed on my folding box which has 2 6128s ( 2 Ghz) and it plays well . I am wondering what everyones thought are and if
you think it is worth it to switch over?
You have to ecuse my grammar and spellng I am doing this just as I feel the first signs of a Migraine, have to digout the Sumatriptan.

my wife is running a single D7770 1Ghz edition and I have to say that card rocks, she keeps right up to me with my 6970 and her with the 7770 we both max out Starwars and many other games and the only difference we notice is on the CPU side her quad core FX vs my 8 core FX and when huge battles happen.

I would just try some benchmarks and tests u have both cards give them both a try

the 7770 should be better + dx11 + less power consumption

its = to a 6850
personally i prefer nvidia drivers

I wished that they made a waterblock for the 7770 I was looking around and seen one but it only fits the7750
