I am planning to build a system in the next month or so around the P4 2.8ghz 800mhz fsb. I had things mapped out, and was going to start with 512 of PC3200 ram, eventually going to a gig or 2. Now I'm seeing that 3200 is showing some age, with speeds up to 4400. Budget is somewhat flexible, so I don't mind paying a little more to get a good boost in performance. Is it worth it to jump up from 3200? What else do I need to consider if I go with the newer ram? does the P4 mentioned above support higher ram? looking to spend around $125 for a motherboard... can I get a good board that supports the new ram for this price range? most boards i've looked at top out at DDR400. any advice is appreciated. thanks!
