FWIW, I just recently built a new system similar to what you have there. The
only big differences are the video card and sound card....I too, was
considering a ti4200 but opted for the ti4600 after seeing a cpl reviews and
comparisions..

I run 1600x1200x32, with everything on high except Structure shadows on
cars. Drawing distance of 100% and field of view at 75.
I would say I avg 50+ fps in online league races....that's a basic average,
there' s some tracks that it drops to 47 exiting T2 or something like that,
but mostly hovers around 53 range...
I don't race offline much, but did see what it'd get....I had full field
showing and everything cranked like above...started from the rear at Atlanta
and it was in the upper 20s-mid 30s for several laps....just on the edge of
raceable....as the field thinned a bit, it jumped up a bit....
Like I said though...I don't race offline much and only league race, so it's
plenty for me....

Intel Pentium 4 2.4BGHz 512K 533MHz CPU Northwood P478 Processor
