Hi all, I've been gaming in Windows 7 under bootcamp on my 15" 2.53 UBMBP for some time now and I'm quite satisfied with the performance. The game I play is Lord of the Ring Online and as some of you may know it is not a new game (~2 years old) but it is quite demanding nonetheless. Just yesterday I was thinking about hooking up the MBP with my old 24" Dell so I can get a bigger screen and higher resolution. However what concerns me is that if I do connect the Dell to the MBP, do I need to close the lid or I can leave it on because as the video card is working it produces quite a lot of heat. Leaving the lid on would be better for air flow. If I leave the lid open, will it be shut off (as in, dark) because I really do not need dual screen, or will I be forced to use it as a secondary monitor as well? One final question, will the 9600M be able to handle the game if I use an external monitor with higher resolution(preferable in 1600x1200 or even better 1900x1200)? Thanks guys!
