OK, I've finally decided that its not the right time for me to build an AMD system, so instead I'm going to upgrade. Here is what I currently have: P4 2.8 with 533 FSB. I *believe* that it is a P4B, but not certain. A dell motherboard. ATI x800 Pro Vid Card Audigy 2 ZS Soundcard 768 in probably mismatched (I think some is DDR333 and some is DDR 400) crap RAM. My MOBO is Dell. I want to replace the MOBO and RAM. Obviously I need something with AGP 8x. Questions: 1. If new MOBO supports FSB of 800 (while CPU only does 533) will I get any performance gain from using DDR400 memory (instead of DDR333)? 2. Will I get performance gains from using Dual Channel Memory, given the processor is a 533 FSB? 3. Whats a good MOBO? I was looking at the MSI "865G NEO2-PLS" i865G Chipset Motherboard for Intel Socket 478 CPU .... Is that overkill for a 533 FSB processor? Thanks in advance.
