With my licence plus is it enough ?
Thanks for your answer.

i think it would be a good idea to buy one. (well, i am thinking of it too...)
at the moment, orders of the 690 can be made, but only with the 1.86 GHz processors. as andrebaros said, the actual dual-dual systems may be still faster, especially for soft that is not multithreaded... as the standard windows calculator... (that may change with windows vista...

)
why slower ? well, four times 3 GHz = 12 GHz. 6 (SIX) times 1.86 GHz = 11.16 GHz. i wrote six times because You'll get only 50% speed increase if You double the cores from 4 to 8 (around 6). (this is just a very simple description without technical details.. ) of course then many smaller differences have to be taken into account. of course that the 8 core version is 1500 dollars more expensive than a quad version !
i will wait for the 2.66 GHz which should be faster. by my «estimation», a dual-quad precision 690 should finish the maxwell render speedtest v. 1.1 in around 23 minutes. that would be a great time !

i'm a little dizzy, hope these words make sense.
