Let me know what you think before i buy it...also i assume the 650w PC&C can handle this, i have never purchased a PC&C but i hear they are some of the best...let me know if this will be enough juice for the crossfire setup...and does anyone know how the bios is on the Asrock Z68 extreme 3, heard a few things about it being buggy? All comments welcome...grand total $1408 for everything before rebates.
I don't know anything particular about that board or its bios. From what I've learned from computers and building them is that you don't want to skimp on the motherboard, pay the extra dollars to get the better product, especially if your going to OC it. Not that I'm saying the ASRock Z68 Extreme3 Gen3 isn't a good board. Sorry, I wish I knew more on that board for you, but I don't. I just got a ASUS P8P67 DELUXE (REV 3.0) coupled with a i5-2500K and it's working great for my other machine!
I know you'd lose the 5 combo discount but, I have a antec 900 and just got a NZXT Phantom Black Steel case for my i5 rig and I like it more than my 900. As long as you don't mind the size! I very much like the fan adjuster right at the top, so you can go to high air circulation and quiet mod easily.
It's 109.99 at newegg right now, I'd recommend this over your case. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
A 650w can easily push two 6870's and leave plenty of head room. And for those suggesting another psu, PC Power & Cooling aren't just manufactured by Seasonic, they are Seasonic's best in regards to non modular psu's. They are about as good as it gets.
