Is it better to get 2 Crossfire Sapphire Radeon 6770 HD or one GTX550 Ti, Tnx in advance

The two cards you mention have very similar performance so it stands to reason that two HD 6770's will be 'better', however it also means you need a more powerful PSU (crossfire certified preferably) to run the two cards and a crossfire capable motherboard. Then there are issues around driver compatibility in games and so on.

Well i think to put in this mobo ALiveXFire-eSATA2 and 400W real psu

The motherboard is crossfire capable but your PSU may not support two cards....the HD 6770 draws 108w under load so requires a 6 pin PCI-E connector, that means two connectors for two cards....you need to check if your PSU has two 6 pin PCI-E cables.
