Since I didn't get any responses in my other topic here it is again under a different title: I have a Dell Dimension 8300 that came with a Pentium 4C 2.8ghz HT cpu and I'd like to rip it out and put it into a new mobo. I wanted to get an Asus P4C800-E Deluxe but it looks like they're discontinued (yeah I shoulda done this a couple of years ago ) -- I can still get this motherboard but don't want to pay $200 - $300 for it. I've noticed that Asus has a similar (?) board the P4P800-E and was wondering if I could use this board instead? I don't understand the differences in the two boards -- the 1st board works on the Intel 875 chipset and the P4P works on the 865 chipset--does this mean that I need to get a different board/chip combo? Sigh, I've been out of the loop for a while now and don't really know what works with what now as I haven't been keeping up. Basically, I'd like to rip most of my components out of the Dell system and put it into a new mobo, case & psu and overclock the system. I know at the time the Asus was the best board for this Northwood processor but if anyone else has any other advice please let me know otherwise I guess I'll scour for the Asus P4C800-E Deluxe mobo.
