I am putting a new system together- M2N32-SLI Deluxe motherboard; AMD 6000+ X2 dual core processor; 2 gigabytes Ultra DDR2 800 MGH RAM, Maxtor Sata II/300 HD so far aquired.That leaves the vid card and the PSU. Question 1: If I get a DX10 enabled card, can I still use it with XP and DX9? I don't plan to go to Vista till FSXI.Question 2: Does SLI work in flight sim? If not I will stick with 1 card till FSXI (if it supports SLI then).Question 3: What wattage power supply would I need to grow into an SLI setup with two 8800 family high RAM cards? The 6000+ is hungry too I hear...Thanx in advance for your assistance.Best Regards, Donald T. :-waveFLYing? It's cool. Trillions of birds and insects can't be wrong.

Q1: Yes.Q2: FS9-No, FSX-Yes (Nvidia supported)Q3: Depends which 8800, if GTX, then a LOT. Websites usually tell how much cards use (GTX=145W), you can make a simple math. Basically, I wouldn't go below 700W for 2x 8800 GTX. And why 6000+? Intels are much better now...
