I haven't heard anything about this. I would say not to worry about it unless you are having some big issues/probelms with windows after your install.

Anyone know of a list of programs that I should set affinity for 1 cpu?

It's interesting that there are still this many problems, that link I posted has info though.

Need For Speed Most Wanted doesn't play nicely with dual cores; I was playing on an X2 4400 and it sped up the game crazily fast!

PLEASE BACKUP YOUR REGISTRY FIRST!!

1 - Install the amd drivers, download it from here... http://www.amd.com/us-en/Processors/..._13118,00.html

2 - read this website and downlaod the hotfix....READ here http://support.microsoft.com/?id=896256 ........Download here http://www.sendmefile.com/00213285

3 - Edit your registry to enable the HOTFIX, follow these steps.
1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Right-click HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Con tro l\\Session Manager, point to New, and then click Key.
3. Type Throttle for the new key name.
4. Right-click Throttle, point to New, and then click DWORD Value.
5. Type PerfEnablePackageIdle for the value name.
6. Right-click PerfEnablePackageIdle, and then click Modify.
7. In the Edit DWORD Value box, type 1. In the Value data box, make sure that Hexadecimal is selected, and then click OK.
8. Quit Registry Editor.

4 - Make sure your BOOT.ini has this command in it, /usepmtimer to check, right click on My Computer go to properties, click on the ADVANCE tab, then under startup and recovery click on settings, then click on EDIT....make sure your boot.ini looks like this

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\\WINDO W S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\\WINDOWS="Micr osoft Windows XP Professional" /noexecute=optin /fastdetect /usepmtimer

OK, since some people switch to single core after having issues with dual core, here is a simple way to remove the Hotfix and drivers.

1 - Uninstall the Hotfix, go into ad/remove programs, click on show updates and remove update numbered KB896256

2 - Reverse the registry entry.

3 - Uninstall the AMD drivers.

4 - Go into your boot.ini and remove /usepmtimer, and your done.
