I could really use a copy of Windows 7 Pro. I have it on my work laptop and love it. I've been running Vista Home Premium X64 on my personal/gaming machine and am so tired of it. I've disabled as many unnecessary services and scaled back the graphics settings for improved performance, but the OS is still so bulky and inefficient. I would even go back to XP x64, but drivers are very difficult to find for it.
