Said computer is likely to have the following specs;Two 2.66GHz Dual-Core Intel Xeon "Woodcrest" Processors, 4MB shared L2 cache per processor. 1.33GHz dual independent frontside buses. 64 Bit.1GB (2 x 512MB), 667MHz DDR2 fully-buffered DIMM ECC (upgrade to 2GB Later)And an ATI Radeon X1900 XT 512MB for graphics.I might be getting it soon but haven't fully decided yet. It'll have XP installed initially and Vista when it's ready.The thing I'm not sure about is will FS9 be able to run with this computer even though it has 2 Dual cores? As far as I'm aware, FS9 doesn't recognize dual cores processors. Is this true? So it runs FS single core but both @ 2.66Ghz?Does FSX support Dual Core processors? When I have Vista installed sometime in the future along with FSX, the OS and FSX take advantage of dual cores?Excuse the empty headed style of my questions. I'm a bit slow when it comes to computers. :(Thanks in advance.Pyjamas

Before even considering a Core2Quatro, Ask yourself what are you going to use this system for? Only for FS?, or are you a heavy user too.

Yeah, FS and gaming is only going to be a secondary thing, at weekends really. Most of the time it'll be working with Photoshop, Lightroom, music software and processing DVDs.The price works out quite well actually @ roughly

Well guess since you do use resource hogging programs too, it would not be a bad choice. That said the progams have to be multithreaded and able to use 4 cores. Be aware though some games do not like 4 core's, for example Call of duty does not work and crashes, i dont know how fs(x) would work...maybe try to get some info direct from MS to start?
