I'm in the process of upgrading to a more powerful workstation, and once I switch over I'll be putting the one I am using now (a Dell Precision T5400) up for sale on eBay.

My current machine is no slouch.  It a dual quad core system and even by modern standards still well up there in power (it starts Photoshop CS6 in 3 seconds and scores over 10,000 on the Passmark CPU benchmark).  It's a perfectly functional, reliable system; I just need even more power for some of my development activities. 

I'm toying with the possibility of making it more attractive to potential buyers by putting a bit more money into a couple of SSDs for it.

If you were looking to buy a reasonably powerful Photoshop machine on a budget, which of these would seem more attractive to you?  I've highlighted the differences in bold.

$1200 for:

Professional quality Dell Precision T5400 workstation, Dell keyboard, optical mouse

Dual quad core Xeon x5460 3.16 GHz processors (8 cores total)

16 GB 1333 MHz ECC RAM (4 x 2 GB FBDIMMs)

Drive C: 2 TB total (2 x 1 TB 7200 RPM hard drives in RAID 0)

VisionTek ATI Radeon HD 5670 1 GB DDR5

Windows 8 Pro, along with a copy of my Configure the Windows 8 "To Work" Options book.

Windows 8 Pro, along with a copy of my Configure the Windows 8 "To Work" Options book.

If you have another suggestion as to what I might add or change that would make it seem more attractive, I'm interested as well. 

Would it seem attractive to say it will have Windows 8 already set up and ready to go?  Or do you think people would prefer to install the OS themselves afresh?  Also, I could sell it with Windows 7 instead of 8, as I do have a license for it; I just thought that having it be set up with a modern OS would seem more attractive.

Thanks in advance for your opinions.
