Upgrading to Venice (SSE3). Reformat?

I just upgraded from an Athlon 64 3000+ (Winchester) to a Athlon 64 4000+ (Venice), which adds SSE3 support.

Will I need to reinstall Windows to get SSE3 support working? If a reinstallation is needed, do I need to reformat or can I just do a repair install?
 
I wouldn't bother unless you were swapping out motherboards too. AFAIK, software that makes use of SSE3 would sometimes check to make sure the CPU really supports it. In any case I don't think it has much to do with the operating system.
 
Yes unfortunatley, you will have to reinstall windows to get SSE3 support. It's just like switching from a Pentium 2 to a P3 back in the day... to get the SSE support the P3 had, you had to reinstall Windows. You will have to probably do a reformat, as a repair just rewrites your Windows directory.

I am surprised that your PC didn't blue screen on bootup... that's what usually happens when you add something new like that.
 
I don't think you need to reformat. A clean reinstall should do it . . . (i.e. what I did after I switched from 3200+ Winnie to 3000+ Venice)
