How big is Windwos 7 operating system including updates? I dunno if 80gb SSD would be sufficent cause I would wana put WoW on the 80gb SSD as well as the OS.

16 GB available hard disk space (32-bit) or 20 GB (64-bit).
windows xp mode requires an additional 15 GB of available hard disk space

I am managing to have windows and wow on the same 60gb drive with around 7-12gb spare depending on how far I scale back the page file.

80GB SSD will be plenty to install the OS & a couple of pieces of software - office, AV, fave game, editing suites (examples). Just make sure you don't install a every bit of software onto the SSD as you'll notice it get full pretty quick!
