I have the dual Tyan 2460 mobo and two MP2000+. Can someone tell me what the fastest MP chip I can put in this board is? 2800? 2600? And the corresponding Ghz? I edit video and have to do a lot of rendering. This system was pretty decent when I got it two and half years ago but I need more power and I'm not sure if it's worth it to upgrade these chips or just get another box maybe with the Opteron?

My current Bios is PTLTD - 6040000 Phoenix ServerBIOS 2 Release 6.0, 10/16/01 which I'm sure someone will tell me to upgrade. I have 1 GB ram.

Thanks for your help.
