I went for Intel and Nvidea, but it’s more important to get the mainboard future proofed in my opinion.
Oh and make sure you use a 64 bit OS if you want more than 3GB of your memory to be used 😮 Not that I’d do such a stupid thing, oh no… All sorted now but I did feel a bit stupid.
I’m running an Intel Core 2 duo 8400 on an Asus P5Pro M/B, 4 GB RAM and an Asus NVidea GeForce EN9600GT graphics card, and FSX pretty much runs at eleven accross the board. Pretty much all of my components ended up as Asus for some some reason but it seems pretty solid – had to reseat a memory module once but that’s been the only issue.
Modern Warfare 2 runs smooth as you like as well so I’m happy for the moment!
