Don't think you'll have problems -- I upgraded my rig with I3 2120 CPU at 3.30GHz and 8GB of RAM. The one thing I'm not sure is if you'll end up with a fully activated copy of Windows 10 if you try to do a "clean install". If you perform an "in-place" update (i.e. install Windows 10 as upgrade over the existing Win 7 installation), it should be fully activated -- once you've got the instance of Windows 10 installed and registered, the electronic registration should allow you to do a "clean install" that will be activated once the computer is able to connect to the activation server, That's the route that I took on my computer -- I first imaged the existing harddisk (just in case something went wrong during the update). then ran the Windows 10 install as an update. I did have a few scary moments as I needed to update the BIOS for certain things to "take" properly (the scary bit came after re-flash of the BIOS and the machine went into a reboot loop --- it partially booted, then sent into reboot -- repeating it several times before it eventually "settled in" -- Not sure how many cycles it went through this, but after the first couple reboots, I'd got interrupted with a phone call, and by the time I'd finished with it the computer "settled in").
The one thing you may find is that the update may remove some software (the Windows 10 install determined that this software was not compatible with Windows 10) -- some of that software could be re-installed (and some could not). What was annoying was amongst the stuff that got uninstalled was the copy of VirtualPC and the VMs installed under it (one of which was the XP Mode VM).
