which is the best ati 5770

i am building a phenome rig with 955be on a asus m4a79t deluxe motherboard.

my question is what is the best ati 5770 card on the market. i have been hearing alot about sapphires vapor range and would one day go crossfire, so what would 2 of them equate to.

i have also seen some new 5770 which sport hd 2.1 and was wondering how important that was and if needed for future proofing.

lastly would i be better off with a 5850hd ati card how much better are they compared to the cost difference, or should i wait for the the elusive 5830hd what is it what does it do how much would it be.

all advice welcome any advice at all as building very soon

These are the best HD5770 1GB cards currently available:

If you can wait a few weeks then the HD5830 may be a good option.

ok guys thanks for that advice might just wait for the 5830, but for a card coming out in a matter of weeks how come they havent released anthing about it

Seems like they are having problems with the design of the 5830 pcb so it was delayed. Could also be affecting the final specs. Waiting to see how they price this.

is there any info on the launch as dnt want to be waiting for ever only to realise that i dnt need them thanks guys by the way

The last I heard it was the 16th of February for the the launch of the HD5830:
