Hi all! I am an FSX fanatic and run the Simulator through 4 cores and therefore have invested in the Q9450. I am also going to use the 9800GX2, with 8GB of DDR2 running either XP 64bit or Vista 64bit. Either or it will be a 64bit Operating System to take advantage of the 8GB of DDR2. FSX is one of the most demanding games on the market and I have been looking at numerous motherboards but am getting discombobulated with the compatibility issues. I have a budget of £300 for the motherboard. Any help on the matter would be much appreciated?
