I'm fine with Vista, but I'd like to upgrade to an OS that looks better, is more stable, and uses less system resources. I've heard nothing but good things about W7. Here are some questions I'd like to ask: 1. Is W7 unstable in terms of app compatability? What [normal, frequently-used] apps aren't supported? For the record, I mainly use FireFox, AIM, Trillian, LimeWire, iTunes, Microsoft Word, u*******, Steam, PhotoShop, and others. 2. How fast is W7 compared to Vista? Keep in mind that I'm running with Quad Core CPU at 2.4GHz per core, 4GB of RAM, and a 1GB GeForce 9500GT Graphics Card 3. Do games run better, worse, or the same on W7 than they do on Vista? 4. Are games supported on W7? I'd imagine anything on Vista could work on W7. 5. How fast is the bootup/shutdown process? 6. Is the UAC as b*tchy as it was in W7? Do you have to click that "ALLOW, DO NOT ALLOW" popup any time? 7. Are there any other things I should know?
