1. Never use an integrated GPU if you plan to do any serious gaming with modern games. Intel CPU's are also much better for gaming these days but do cost a little more. But at ~$300 for an unlocked i7, it's not that expensive anyway.
2. Cannot answer without knowing your budget and the resolution of your monitor.
3. Windows 8.1 (and a few tweaks) have made a drastic difference in my acceptance of Windows 8. I still prefer 7 but 8.1 with a few tweaks is now wholly acceptable as a daily use operating system.
