... that said, A64 3000 or P4 3.0 will NOT bottleneck the x1950p [noticeably/practically] and you CAN crank up the AA/AF and details so your CPU will not be a problem whatsoever.
My own upgrade from x850xt>x1950p is not [obviously] bottlenecking the proc
You seem to misunderstand the situation & what we've said.
The GPU does
not offload work from the CPU anymore at hi res than at low res.
IF the CPU was too slow in the 1st place cranking up the res will
not help the situation (if that's what you meant?).
If you have a CPU which was too slow to handle the most CPU intensive moments of a game/benchmark ,say a P4 1.3GHz & you benchmarked it in for example Farcry, at the lowest res & detail (e.g. 640x480,so the vid card is not a bottleneck) with an X1950 Pro & the FPS was 10 ,if you cranked up the res to 1600x1200 the FPS would still be ~10.The CPU load is the same regardless of resolution (unless you go way beyond the grx cards limit).A min of 10 FPS would naturally be unplayable.
Though if you had a faster CPU which was able to 'supplie' a min of 30FPS then yes you could wang up the res & detail* & make very good use of your shiny new 1950 Pro

,in that respect the CPU would not hinder playability at hi res.
(*excluding details which relie on the CPU)
As I said though,I do agree that a Ath64 3000 or a P4 3GHz is likely to be plenty fast enough to play modern games.Benchmarking at a low res would confirm/denie that.
Btw the bit you quoted wasn't written by me

If your minimium FPS in a low res is 30* or above then you can make good use of a 1950 Pro ,your CPU 'limitation' won't be a problem as its above the min threshold
*min acceptable FPS depends on the game & personal preference ,30FPS leaves a little safety margin.
To find out if your CPU is fast enough benchmark your rig at your normal resolution & work your way down resolutions until there is no increase in FPS ,at that point that is the max FPS your CPU can provide.
If your card is sufficently slow enough in the game tested that you don't reach a FPS plateau then you need to use FRAPS for many games (except Farcry) to measure what the min FPS is within the whole run of the benchmark.
I hope that lot makes sense
