I have the same dilemma. I have a 23" all-in one from HP with quad core AMD and Radeon HD 7660 D. I have the xp 10 demo loaded and I'm impressed to date but I'm unwilling to go for itjust yet. I will watch the forums like a hawk to see if there are problems using my Saitek X45, or using landing aids, GPS and so on. It's important to me to use a simulator rather than a game.
