Best way to find out is to try it. Just ensure you have a backup and a plan B if it doesnt work or it too slow for it.
7 runs as fast as or faster on my Pentium-M 1.1GHz Fujitsu than on my Pentium-M 1.6GHz Thinkpad and Pentium-M 2.0 Toughbook. I'm hoping to get more tablet features on my Fujitsu with 8/8.1.
As suggested by cocachris89, test is the best you could do. Check about to be able to run without NX Support which was discussed several times already at this forum. And you'll be limited to use 32bit only!

Guess that was enough for Win8 ? lol Code: Advanced Technologies Intel® Hyper-Threading Technology ‡ No Intel® Virtualization Technology (VT-x) ‡ No Intel® Trusted Execution Technology ‡No Intel® 64 ‡No Idle States No Enhanced Intel SpeedStep® TechnologyNo Intel® Demand Based SwitchingNo Execute Disable Bit ‡ Yes
