4. I'd go with a single 5850.

5. The Corsair has more usable power(41 amps instead of 40 amps), is rated for full output at 50 C., and overall is a better PSU.

^+1... 4) & 5)

1) ASUS MOBO, since going with 5850 and PSU not strong enough for two 5850's so the PCI-e x4 will not play a factor.

2) Again ASUS MOBO, since PSU not strong enough to crossfire two 5850's.

3) Crossfire at x8,x8 is acceptable. You will see a slight performance decrease at 16x,x4.

but my question is if i get 2 5770s....will the msi gd65 be the available option or should i go with the asus p7p55d ?????

i am leaning a lot towards having two 5770s in crossfire.....as because the performance will be a lot like a 5870 ....as i have read from the various reviews.......

and will VX550 be able to power two 5770s in crossfire ?????

Which CPU are you going to install? And why crossfire instead of a single card? Especially with those motherboards.

Here is a neat tool to calculate your power requirements: http://educations.newegg.com/tool/psucalc/index.html

Hope it helps

well the power calculator provided in the antec website tells me that i will be requiring about 498 watts having a crossfire of two 5770s
but the above stated says that i will be needing 609 watts...

which is correct ???
help me out !!!

WILL CORSAIR VX550 BE ENOUGH TO POWER TWO 5770s IN CROSSFIRE ???

Frankly, for a crossfire configuration, it seems a little tight. And you still haven't told me which CPU you were going to use.

No need for double posting, you ain't gonna get an answer any faster.

For what I can see, even the 600w won't be enough. Personally, I would forget the crossfire and install only one video card. Especially with those low end motherboards that you've selected.

But i could be wrong.
