New Rig, MB decisions ... ug

[Superslayer]

Hey all. I'm building a new rig that will primarily be used for a work machine, not gaming. I'd like it to be as 'future proof' as possible, but also do not need many of the perks associated with 'power-house' machines. My motherboard budget allows for a maximum of $110 including any taxes and/or shipping price. Discounts are good if they bring the price below the 110 mark, and here are a few requirements.

• USB 3.0*
• 1 PCI-E 2.0
• AMD3 Socket/Phenom II for a Calisto 955
• No onboard video
• 1333 compatible memory
• 1 Pata
• Core Unlocking ability
• ATX
• Sata 6gb*

* at least 1 if possible

At the moment, I have the CPU, one stick of memory, the hard drive and a hand me down GPU

CPU : http://www.newegg.com/Product/Product.aspx?Item=N82E16819103846

I shop only on newegg for computer parts and am torn on a selection of 3 of them:

ASUS : http://www.newegg.com/Product/Product.aspx?Item=N82E16813131656
MSI : http://www.newegg.com/Product/Product.aspx?Item=N82E16813130275
MSI : http://www.newegg.com/Product/Product.aspx?Item=N82E16813130558

Any input anyone can offer would be greatly appreciated.

I'm watching these because I'm thinking of putting together a new rig too.

Ya, the G55 was just on sale over the weekend for 5 less dollars and I couldn't pull the trigger, they all have what I'd want, but each lack one thing the other(s) has/have. I do take into account user feedback, and that alone can be difficult.

I dig mine HERE but it has on-board video. Everything else hits your list though.
