Well I can answer my question now - it looks mighty fine for a flightsim pc !!!
The old XP installation screamed and yelled and sulked when I tried to transplant it into the new box so (after a last minute dash to The Warehouse for a usb mouse) I did a clean install of windows 7 onto one of my backup drives, did the big FSX/SP1/SP2 install, put zonealarm on, and recreated the flight from yesterday which was default C172 from NZAA to the city in spot view then to NZWP in the VC.
Yesterday on the old computer on the way into the city I was watching a 7fps slideshow. Today in the new computer everything was just sliding sensuously along like swimming in a cool pool on a hot day, with the fps sometimes dipping into the 20's but generally between 35 and 50.
Yesterday there was a marked improvement when I changed from spot view into the VC, with the frame rates generally managing to stay in double figures. Today there was no such improvement, but I can cope with the disappointment and live with 45-50 fps from the VC.
After the NZAA test I tried something a bit more adventurous - I took off from KJFK and flew a loop around Manhattan Island at 2000', low enough to be able to wave to the people driving along in their cars, and landed back at KLGA. As expected with so many custom buildings and several big airports to worry about the frame rates did drop down, they generally sat around 21-22 fps. I did notice them down around 17-18 a couple of times but only because I'd chosen that moment to look, I'd never have known it just from the behaviour which was consistently smooth although not as silky smooth as the hick town down under.
I must point out that the results aren't directly comparable as yesterday on the old box I had the quick config sliders set to just under half, today on the new box they were maxed out. A quick peek under the hood showed the nitty gritty sliders still had plenty left to give (what the heck do you need to run this thing *really* maxed out ?????) but the main sliders were on the stops.
Happy camper, and special thanks to Doug for suggesting the grunty cpu.
Cheers
Gary
