I'm a little unsure about the Mobo. and a few other things like whether or not the PS will be enough for the CF. I'm planning on using Vista, 1600x1200 or higher resolution on it. This is all in CAD and I just found the prices straight off of Canada Computers, not NCIX since there's a store close-by. I'm just hoping that the prices drop during boxing day cause my budget is only about 2000$. Thx again.
Regardless of a PSU being "rated" for SLi or Crossfire power demands on PSU's can be brutal. The ATI cards you have choosen are power hungry. Then factor in overclocking and the accessories that need power (back lit keyboards, wireless mice etc) its better to have a PSU that is running at a gentle level rather than maxed out. That also means its fan will not have to be ramped up thus quieter.
Think of it like a car. Sure that little 4 cylinder can go 100mph but its working for it. That 5.0 V8 is just cruising and hardly working though.

The ATI cards he has chosen together pull about as much wattage as one HD2900XT. They're not all that power hungry.
Lol at the choice of the Rosewill PSU. I wouldn't put one of them in the system, but the ABS one was a great choice.
as for the PSU, how much watts would the PSU need to be? i'm seeing about a range of 700~850 watts from the ones you guys mentioned. how much watts would I need to do some overclocking on the 3870s? I just figured that 600watts was enough
Akhilles is right about the Rosewill PSU. Its not very highly recommended but I just wanted to show you whats out there and it was on the same page The link above is for a local Canadian vendor I use alot..
Go to Ati link I posted. Under the HD3870, any of the psu's is fine. Yes, I would pick out a more than enough psu so that it won't be stressed at all times. A larger psu will last longer, & run quieter.
