that would work but there are better options available since you have the upgraded power supply:
1.) brisbane class 5800+ (3.0Ghz), rated better than the 3.1GHz chip # ADO5800IAA5DO

2.) brisbane class 6000+ (3.1GHz), highest clocked chip # ADV6000IAA5DO

UPGRADE BIOS to 1.1.11 with your old processor then upgrade to the new and your done.
to update BIOS first.
get BIOS it is on Dell site and you should know it's runs well from in windows, no need to try to flash BIOS on start-up.
so download from Dell and run it once you save it to your desktop. run from within windows..
unplug all USB devices except for mouse and keyboard if they are USB keep them plugged in. run the BIOS.
it will reboot and your done...

YOU WILL NOT NEED AN AFTERMARKET COOLER, STOCK WILL WORK FINE WITH ARTIC SILVER 5 THERMAL COMPOUND..
go back into case with a phillips screwdriver and unscrew the two retention screws that secure heatsink.
carefully pull up and out as you will see round hinges on the other side from the now removed screws.
remove heatsink and put aside, now to the cpu socket, lift metal lever on side to release cpu lock.
if using your hands and not some 'grapple' type device, put your thumb at the bottom and another finger at top and lift up at the same time,
you do not want to chance bending pins just in case.
with new cpu, make sure you line up the four indents within the bottom of the cpu with the indents in the socket, only then it will have a secure fit
and work properly. once in lower the locking lever and grab the heatsink.
with a now clean heatsink and freshly applied thermal compound (i use spread technique and not pin drop method), re-install heatsink with
round hinges going in first, line it up and re-insert and tighten screws. you might have to move the heatsink around to line-up screws but don't worry
about touching it, no damage will be done. tighten up screws, reconnect all cables and power lines, double check fan connection.
close case, plug her up and boot.


WOW! VERY DETAILED!!!!!!!!! GREAT! OK I found that my local computer parts store carries the thermal grease (I called them up asked "whats the best thermal grease you have" and guess what he said? "ARCTIC SILVER 5" < that put a huge smile on my face :D ) anyway, I'm gonna go with the 5800 and follow all of your directions really detailed and great. THANKS!

my Dell unit I call my 'daily driver'; nothing special just a slightly older media friendly unit for 'daily crap'.. I have 2 similar models.

Athlon 64x2 6000+ (3.1GHz) Brisbane
E521 (modified) / Foxconn / Dell UW457
Noctua NH-U9B cpu cooler - AS5 thermal compound
4GB (2x2GB) Elpida DDR2 800MHz CL5 - 5-5-5-18
PNY nVidia GT240 - 512MB DDR5/HDMI

ASUS DRW-24B1ST DVD-RW SATA
5.25in twin fan case cooler / 3.5in card reader

That is a good solid build all HQ stuff.
I love having a dual display myself. Much more productive.Plus just cool to showoff.
I just bought a HP G61-511WM laptop with AMD Sempron M100 2.0ghz single core plus
250gb sata II HD,DVd-rw DL Lightscribe, 3gb DDR2-800,ATI HD4200 IGP with 128mb sideport ram up to 1500 shared, HD widescreen for 175 cash.
Just needed an OS and has a Win7 Premium COA.Grabbed an OEM disk and works sweet.
I love Craigslist and people who mess up their computers LOL

To the Original Poster
It is a nice thing to do to pick a Best Answer (will see check box under replies)
Whoever gave the answer will get points and so will you.
It is a good thing.

o.0 It didn't get posted... well here it is... Do I NEED to downgrade my BIOS from 1.1.6 to 1.1.11? On another forums (double the chance to find a good answer, right?) The guy is said "The C521, the board is a Dell Proprietary board and not designed to handle the load, in the later models they offered a x2 6000 but the board was a different part numer and it still didn't last." and "Never had anything past the 5600 work correctly on a C521 let us how it works out. " so naturally I'm still a little worried, and what are the chances that Installing the new CPU won't work?

The op said they were going with the 5800
Plus he has a 9600gt
good multimedia and light gaming rig
If he is a serious gamer he will need to upgrade from the 9600gt
Everything I seen says to go with the 5670 low profile (slimline tower)
Just researched low profile cards and that is supposed to be the best
