will an upgrade to Win7 Pro cause any OC issues?

Call me cautious, but I thought I would check here before doing the "Windows Anytime Upgrade" from Win 7 Home to Win7 Pro on my son's overclocked P67 Ode Level 3.  Any potential here for screwing things up with the OC, or should I go ahead with the upgrade? 

The virtual XP download program allowed with the upgrade might help me run some programs that have not updated to work with Win 7.   

Lol... I just do the buying and interrupt him for upgrades & occasional system admin chores for his system... He's on that Ode about 15 hrs every day..loves it! Overclocking is new for me, so I try to ask around before making changes that could shut him down.

Next month it's finally my turn.... I plan to order a nice DS X79 rig.....

You do have a point sir, but I liked what I have read on the i7 3930k. I don't think I'll be able to upgrade anything for a few years, so for me the 3930k is a long term performance choice.

There is always an improved piece of hardware just around the corner....but this rig should do all the jobs I'm after now and still be a quality fast platform when it needs upgrades several years down the road. I think I put some smart components in this box....:-)

Nope, the OC will be just fine!

If you have a chance let us know how the upgrade turns out 

Thanks for the input gang.
Upgraded from Win 7 Home to Win 7 Pro without any issues!

Thanks for the very reasonable suggestions Orange...and everyone here. I have had no PC of my own to use now for many months (keep getting kicked off my wifes Qosmio laptop and the son's DS Ode 3) so I really can't delay this much longer. I have to go a long time between builds, and while I would want to update a new build to the next gen Intel processor if it does perform as well by comparison as rumored, I may not be able to spring for a new CPU quite so soon. I wouldn't be happy getting stuck with the 3820 long term. I figure the 3930k should allow me to hit the performance levels I want for Lightroom /Photoshop, multitasking and handle triple screen gaming well. If I were to be able to upgrade to the next gen CPU late next year, then I'd have a strong 6 core 3930k CPU spare available to start a second build with....

I have reconsidered and tweaked my earlier planned build a bit though.

Changing to the outstanding Corsair 800D case, and will use the DS option to add a fan intake over the graphics cards in the side window. Guess that option isn't possible to mod the 650D window, and I don't care for the full mesh replacement version COrsair offers. Going to use the new Corsair Neutron 240's in RAID 0 as my C drive...great review on overclock3d compares it's tested performance very favorably with the more expensive Intel 520's. A little risk in reliability going with the new Corsair drives but worth a try in my opinion.

I'm researching the monitors on TFT Central & PRAD, but I plan to go after 3 Dell Ultrasharp (2410 or 2412m) or 3 Asus Pro Art (PA246q or PA248q) IPS 24" at 1920 x 1200. Leaning towards the less expensive E-IPS 2412 or 248Q panels with LED-W back lights that should also seriously reduce power use & heat generation of 3 panels. At 5760 x 1200 or 3600 x 1920 resolution, I think I should probably spend a bit more for a pair of the NVidia 680 4gb cards to drive them at best possible frame rates.. (Saw a thread that several cards of the NVidia 700 series in 2013 will have 3GB vram on board instead of 2gb in a nod to the increase of vram use by heavily modded games such as Skyrim, game designers using more vram in future plans, and proliferation of inexpensive multi monitor gaming)

I'll try to post the build but I hope to get it all hashed out and ordered in the next two weeks.
