Newegg.com and geeks.com for a SOCKET 478 board. Be sure to get some fresh heatsink compound too.
I am wondering if anyone knows what other type of motherboard would be a good replacement for an Asus p4s8x-x mobo? I'm looking for something along the lines $110 with an 8xAGP vid card? other than that my processor runs intel Pentium 4. and thats pretty much all i know. Any other pointers would be greatly appreciated. Thanks.
