Windows 7 - Dads home office computer!

Hello,
I'm currently in the process of doing research for my dads home office computer.
He would like the have the ability to run multiple software applications that he uses for his work.

The programs that he uses aren't very graphical intensive so I don't believe a super high end workstation is require. Which is the reason i went with AMD i figure Intel would be too powerful for what he needs?

He has a 30 inch monitor he uses now and would like to hook up his smaller 16inch display for a dual monitor configuration which is why i'm thinking about this particular GPU here are the specs I have so far.



ASUS M4A88T-M/USB3 AM3 AMD 880G USB 3.0 HDMI Micro ATX AMD Motherboard $99.99

SAPPHIRE 100293L Radeon HD 5570 1GB 128-bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Ready Video Card $59.99

Everything listed can be found on newegg.

P.S. It looks like i might need to find a different motherboard as I don't believe it suppords SATA 6 which i would like to use for his SSD.

Thanks for the help!

What model is the 30" monitor? And what model is the 16" display? Do you know if they accept VGA/DVI/HDMI?
