"Everyone tell me what they think"
- Well, I think you have an awfully expensive CPU there, and is
looking to finance it with a "reasonable price" video card.
(That's easy: ATI Radeon 9600, 9600pro. And FX5600, FX5600ultra.)
- But why?
Lets stop for a while and consider what you're going to use your
machine for. Your spec is optimal for mpeg&videoencoding. That's about
it, period.
Much better balance for games&mpeg&video is 2.8GH@800FSB (which I
think you can get for $260) and Radeon 9800nonpro (approx $250).
That's cpu + graphics for about $510, compared to your planned
$542-$642, with performance about equal to your $642 alternative.
Even better game performance for your money then, is mainly achieved
by upping video, up to FX5900ultra, not by upping cpu.
(Stick to the 9600pro, and you get away with $430. And odds may be, by
the time you start feeling limits, it's time for a new generation
videocard anyway?)
To repeat my main message: Maxing out game performance above 2.4GHz,
is not mainly achieved by putting lots of money into the cpu.
Differences between 2.8 and 3.2 are small. The FX5900 and ATI 9800 are
a world apart from everything else as videocards. It makes better
sense to use $100 to $200 to up your video instead.

You also claimed the 3.0@800FSB outperforms the Athlon XP3200???
Well, I can only assume your main interest is in video & media, and
that you have visited anandtech's pages after pages of SSE2-optimized
Mpeg encoding benchmarks, that they for some reason, offers for
"comparisions".
- The P4 excels at mediacontent! It does well on all simple chains of
monotoneous, nonconditional instructions, thanks to its clockrate. But
it does even better with SSE2. It's also a good choice for games,
where the 2.8-3.2@800 often have a tiny edge on XP2800-XP3200.
At least as long as the AI is not too complex. (Interesting
observasion: Most games benchmarks do not include impact from complex
AI.)
Other sides of life are, - that on general applications benchmarks,
the 3.0GHz@800 is no more than a match for the XP2200+ (that's where
the "+" comes in.

). The Athlon also packs a very mean '87 FPU,
which together with its excellent branchhandling (and the P4's
terrible branchhandling) means that on traditional '386-'87 apps,
about every single Athlon XP still in production, beats the top 3.2GHz
Intel P4.
Question is, if that's relevant for you? Are those kinds of tasks the
ones that bogs you down, and you have to wait on? My guess is, that's
not the case. One has to remember, that even at conditions where the
P4 is performing poorly, its screaming GHz still drags it along at
speeds comparable to a theoretical 1500HHz-2000MHz Pentium III.
Most home users probably have media content as their bottlenecks, with
games as the really performance critical app. Between mouseclicks, the
P4's 'poor' general performance is mostly not noticed. The things you
usually have to wait for in graphics&media, are the ones the P4 does
well (provided you have a P4-optimized app). So the P4 makes some kind
of sense for people with lots of money to burn.
(Me, personally. I'm not in that cathegory. I'm in the
supercomputer-need cathegory, with multi hour calculations, so I'm
really ****ed tired of my P4's. Never again. I'm really happy with my
XP3000+!)
(Mind you, the Athlons are no sloths, even on media, and XP1700-XP2800
are beyond_terrific value. Chr**, you get the XP2500 for 90 bucks! If
I wasn't waiting for the A64, my old slow P4's (1.5/PC100, 2.4/PC2100)
would get heart&lung transplants today.)
