Im also wondering if the power supply will be enough for me to overclock the CPU and GPU. Im also planning on crossfire in the future so will this be enough? Any ideas to make this a little cheaper?

Grab the Extreme4, more features last time I checked. If you are only gaming grab a 3570K instead. The power supply chosen is fine, solid unit built by Seasonic which is the god of all power supplies.

The Extreme 4 is the minimum.

The Pro4 does not have the PCI-E slot speeds you will need.

The Extreme 4 is not a full sized ATX board, and it also is fairly thin.
Otherwise it is similar to the Extreme 6 board.

If I were building an $1100 or more system, I would definitely get the Extreme 6.

This is for what, gaming?

The i7 is a waste of money. The only difference between it and the i5-3570k is that the i7 has hyperthreading, which games don't use. (Which means there's no reason for a gamer to buy an i7.)

Get the extreme4 - it supports future crossfire, among other things.

I'd get a seasonic or one of the more expensive lines of Corsair; that's actually made by a different company and isn't an amazing PSU. (But 750-800w is the sweet spot to power two high-end graphics cards and the CPU, both overclocked.)

Other than that, you have one beast computer, my friend - this is going to serve you well. I have only two recommendations:

1) Spend the little extra money to get a 128GB ssd. (The Vertex 4 is the best value wise.) It makes a HUGE difference as to how fast your computer "feels." (And if you play MMOs, installing them on the SSD completely gets rid of loading times.)

2) Just as a matter of personal preference, check out as a keyboard the Microsoft Comfort Curve 2000. It's really well built, and easy to type on. It's also the only keyboard I'd recommend or use that isn't a mechanical board.

ok thanks! Im moving it back to i5, so in the future, besides of upgrading, could I just buy another 7950 and make it just as fast if not faster?

 

[dumbfounded425]

Oh and can anyone recommend a cheap (lower price for high quality) psu? Anything that can run this with crossfire and full OC so I guess 850w?

I thought it was the V2 version.

The one you picked @ $90 after rebate is a great choice at a great price.
It's made by Seasonic and has the 4 PCI-E 6+2 pin plugs you will need.
Don't change it.

^ Really? I didn't know that Seasonic made that model. My bad.

And OP, you can add a second card for sure, but don't expect it to double your performance - drivers are never going to be that good, so you're going to get 80% at best.

So newf, I could do 2 7950s in overclock mode and cpu overclock?

 

[completelyrandomname]

Yep. More than enough headroom.

 

[dumbfounded425]

ok, 2 questions, Would a razer lycosa make a good keyboard? And How high do you think I could overclock GPU and CPU?
