What's the best 775 processor I can get for my Asus P5GD1 mobo?

That has a 915 chipset right? If so you can't go over a P4 w/HT, That being said I am not sure how fast they go, I know up to 3.4, possibly 3.6. I don't know if it would be worth it to upgrade though.ch5richards

They go up to 3.8 Ghz, if that makes a difference. :\ 

only single core processors so probaly a petium 4 3.4gz but it won't be worth it to buy it because its not much better than the one you have so i would recommend you get a motherboard that supports core 2 duo mastershake575

I don't want to get a new mobo because the P5GD1 only supports DDR1, which means I'd have to get new DDR2 RAM as well.

Easier said than done... no one is hiring around here.

if you have your motherboard manual it should list all supported CPU's

Also you could probably check your motherboard manufactures website and get it there.
