I have a p4c800e deluxe with a 3.2 ht Prescott and was looking at this combo
ASUS K8V-X ATHLON64 S754 K8T800 DDR AGP8X 5PCI SATA Sound 1000LAN
Motherboard
AMD Sempron 64BIT 3400+ Processor S754 Palermo 1.6GHZ 256K L2 Cache 90NM

can use my kingston pc3200 ram and ati x800 256 agp and same case and power
supply 550watt thanks
This article can be used to compare S754 to S939. As near as I
can tell, the Sempron 3100+ is a S754 processor, and speedwise
it seems to be about 400 less of a processor than an Athlon64.

The Sempron P.R. ratings are compared to a Celeron.
The Athlon P.R. ratings are compared to a P4.
Since the P4 is more powerful than the Celeron, due to the use
of more cache, it should be clear that a high P.R. value on
a Sempron is not worth as much as the Athlon64 P.R. value.
This site will give you a lot more benchmarking info to
play with. You should consider carefully what you use
your PC for, then concentrate on those benchmarks. Each
processor family has its strengths and weaknesses. If you
were gaming, I wouldn't hesitate to recommend an AMD
solution, but for most other comparisons/purposes you
really have to study these charts to see what is a better
solution.

For example, if you look at the "Farcry" benchmark, the
Athlon64 is putting a serious beating on the Pentium4
processors. Even a 2800+ Newcastle Athlon64 beats your
3.2E Pentium4. If all you did was gaming, that makes
the choice easy.
If you look at the "Mainconcept" encoder benchmark, your
3.2E is faster than an Athlon64 3500+. Same for Windows
Media Encoder. To consider the AMD platform, you need to
weigh how important performance is in each area, and then
decide what to buy.
When it comes to encoding, the software tools you use
make a difference. Some of the tools will be tuned for
the Pentium4, and it may be harder to find tools that
excel when run on Athlon64. The latest Athlon64 has
SSE3 instructions added to the instruction set, but not
all tools will recognize that the extension is there,
and may not use SSE when running on an Athlon64. This
is one area, where downloading a patch for your
encoding tool can do as much for you as buying a
processor upgrade.
