I have to agree with every word that zeebra posted in #10, MS, though they have controlled the market for years, with UEFI & Windows 8, has tighened the noose more. But here's the problem. Most Windows 8 users hates the OS & many have downgraded to Windows 7 and/or explored Linux options. As for myself, I've been using Linux Mint since the summer of '09, it was named Gloria then. My first attempt was Ubuntu via Wubi, that was a disaster. Tried the standalone Ubuntu, PCLinuxOS & a couple of others before sticking with Mint. It's a great OS, well funded & supported by other means & has an excellent community. And as stated in my avatar, Mint 15 (Mate) is my primary OS.
When MS introduced their latest crap (& I do indeed mean another word beginning with "s", but crap will do on an open forum), they literally shot themselves in the foot. This is the real reason that Steve Ballmer is leaving, he thought that he could create an Apple copycat & has failed. No matter what becomes of Windows 8, it's going down as a failure (worse than Vista) & MS is now at a crossroads as to their future. Fortunately for the OEM's, they're allowed to still distribute Windows 7 computers & they're still selling well. Dell has actually played with Ubuntu distribution, but with little success. Other OEM's, seeing the light, has also started distributing other OS's, in particular, Google. I don't know much about the OS, but do know that it's not freely available for download.
Like zeebra stated, if nothing else, build your own. I am considering it myself, though my issue is, from a hardware standpoint of view, am a Intel/Nvidia fan, which some Linux OS's doesn't always play well with the latest Nvidia GPU's (I recall Linus giving the Nvidia rep the middle finger). So I'm at a crossroads here myself. I refuse to buy a Windows 8 desktop, though I can get the same make/model (Dell XPS 8700) with the latest i7 that has a 1 GB AMD Radeon™ HD 7570 GDDR5 (some models has a NVIDIA equivalent). Here's the model I'm looking at, but still unsure of build or buy. Lots of recent, top notch hardware for the money. That CPU alone costs $349 @ Newegg.

This, I believe is the AMD GPU in this unit, as the AMD Radeon 7570 is GDDR3, the Dell OEM variant is GDDR5, as advertised in the above link.

Still, for $799 + 30 shipping + sales tax, it's a good buy, lots of hardware for the money & being a Costco Warehouse member, the 1 year warranty is doubled to 2 years.
I'm going to find it hard to build that much machine for the money. So does AMD support Linux better than Nvidia?
I'll be dual booting with Linux Mint myself on the computer. The main reason that I need Windows is because my granddaughter has a hard time with any Linux OS (even the kids ones). She's only 7 years old & likes to play her games that are written primarily for Windows.
And the reason that I truly need so much under the hood is that I like to run virtual machines that can perform as well as a native install. Wimpy computers doesn't run VM's so well. BTW, as soon as that PC is ordered (assuming that I do), 16GB of RAM will be ordered on the same day, to give me 24GB total. That will allow me to run 64 bit VM's with 6GB RAM each.
My concern is also in line with this thread, or I wouldn't have brought it up. Even with Windows 7 preinstalled, it still will have the UEFI BIOS (don't know if Secure Boot is a Windows 8 only feature). Hopefully Mint will run good on a modern machine.
Am also glad that the OP is enjoying initial success, hopefully I can do as well.
