Hello everyone'First, a thankyou to all who responded to my query on upgrading to Windows 7 a while back. I upgraded this past week to W7 and added another 4G of ram, total of 8 now. In the process the fan on my GT9800 died and the card quit. (hoping a new fan will bring it back to life) Between the video card going and W7 constantly denying me permissions, I just about went mad, but In the meantime I bought a second hand GTS250 to replace it and that seems to be doing ok so far.After installing FSX I installed the PMDG 737NGX. The install went smoothly and the online activation went without a hitch. (Nice stuff)What I'm wondering is whether the Acceleration pack will enhance the NGX? If not I wont bother to purchase it.All the bestEd Burtonwww.737ngxca.com

Don't bother with accell, just use SP2
