Hi i am looking to go Crossfire with 2 HIS Radeon 7850's here are my questions;

I am going to upgrade to windows 8 will i notice a performance difference?
Im running a Seasonic 620 watt PSU will this be sufficient?
other parts are:
Intel i5-3570k(at stock settings)
16 GB Gskill ripjaws 1600 RAM
(quick side note on this whenever i try to go dual channel with these i get a loud beeping noise and my computer reboots should i be concerned?It works fine in single channel mode however)
ASRock Z77 Extreme4
CM hyper plus cpu cooler

Thanks in advance!

you will see a small performance improvement when going to win 8
"600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology." http://www.amd.com/us/products/desktop/graphics/7000/78...
what slots is your ram in? for dual channel it should be in slot 1 and 3 or 2 and 4

You won't notice improved performance with Win8.

The Seasonic is sufficient.

yes you will see performance improvement...small but still improvement..my windows performance score increased too
I would contact asrock as to why you can't get dual channel to work..with dual channel your system will be faster
