2 480s for sure.
Multi GPUS don't scale well, and BTW the 5970 is 2 5870 not 2 5850.
Also, Prehaps seek some preshional help for that?
5970 is 2 5870s underclocked to 5850 performance.

i have the 5850's on water also,so the rads and stuff are all ready installed,maybe be able to keep same mobo then if i just go the 480 route.rosewill 1000w enough for sli 480's?
No, you will need a bigger power supply. That power supply shouldn't even be used to power your current system, it sucks.
I recommend this:

This is what happens to a bad quality PSU, though yours is likely a little bit better:

to be honest i just cant stop obsessing over upgrading this computer.i know its not necesaary,i just keep trying to up my vantage score,which means nothing really
If this is based off of Vantage scores purely, you need to stop looking for an upgrade and seek immediate mental help. If you are dissatisfied with performance in a game or future performance then go ahead and upgrade, 2 GTX 480s will rape future heavily tessellated games and everything in-between.
Since you are on water you should get 2 GTX 470s and not 2 GTX 480s, the only real-world advantage of the GTX 480 is a better air cooler. Clock for clock they are less than 10% away from each other, an unnoticeable amount, for far less money. If you can't afford waterblocks for 2 GTX 480s, getting GTX 470s instead will give you the ability. Also, GTX 470s are infinitely easier to obtain. Remember, the GTX 470 has a 6-7% decrease in SPs, TUs, and ROPs, they performance difference is only because of the clock differences. The only time a GTX 480 will justify itself, even slightly, is when using high amounts of AA at resolutions of 2560x1600 or higher because of the extra memory.
