Tom,
Your CPU looks fine on both of those. The only question is the GPU. Scenery is now cached in the CPU VRam. If you have 512, it might run out of memory with ORBX scenery, and quick. You simply will run out of memory with ORBX, but if you lighten the load (low settings) you will extend the time and possibly not have memory crashes. But, if you have a GPU with say 1 Gig of VRam, you should be good to go.
This is on 'V2'. You are fine with V1, 1.4, but man, I would try for V2.
I have V2 on my laptop, ultra thin Vizio and it runs it fine. I haven't tried spiking the settings on it though, stock installation.
