I'm looking into replacing a 6800GS AGP in a kid's PC that's running
very hot and has even caused intermittent shutdowns. The highest
recorded temp was 270F. Yikes! I've since cleaned the case thoroughly
and provided better ventilation, but it's still too high for my tastes
and putting a lot of stress on a noname power supply.
Today I saw a cheap 8400GS PCI (yes the original PCI) that got me
wondering exactly how even a crap 8x series card might perform compared
to the the older 6800GS. At first glance the 64-bit bus and limited PCI
speeds would seem to be a big disadvantage, but I've had a hard time
finding benchmarks of a 8400GS let alone comparing the two. Tom's VGA
charts have been no help.
I know a 7600GT PCIE is slightly faster than a 6800GT PCIE and that a
6800GS AGP is quite a bit slower than a 6800GT, but that still leaves me
with no reference point for the 8400 PCI. I don't recall seeing
articles of any newer PCI versions lately (can't blame them). I know
it's going to be bad, but just HOW bad?
A bottom-feeder 8400GS won't be capable of running anything shader-heavy, so
you may as well look at basic fill rate and memory bandwidth while playing
older games. http://www.techarp.com/showarticle.aspx?artno=88&pgno=3
The 6800GS AGP does 4.2 Gtexels/s and has 32 GB/s of memory bandwidth. The
8400GS does 3.6 Gtexels/s, but has only 6.4 GB/s of memory bandwidth. A
close equivalent to the 8400GS would be a Geforce6 6600 non-GT.
BTW, a 6800GS uses less than 40W at max load. A 8400GS may not improve much
on that figure.

The one You are interested in won't be needing much less power from the psu.
What You could try is remove the heat sink from the GPU, clean everything
very thoroughly, apply some new heat conducting paste (just a little bit,
more != better, You just need it to fill out the "microholes" in the
surfaces of the GPU and the heat sink)(maybe a strange word, "microholes",
but I don't know what the correct word is in English) and put the heat sink
back in place. I have "cured" many CPU's and GPU's that got to hot this way.
