AMd will be better for you, a tbird 1.33g on asus a7a266 or even a7m266 if you are keen on ddr.
dont get p4 just yet. its intel's stock clearance sale and newer p4s and the boards will be incompatible with the current one, since they will be socket478 against current socket423. wait for northwood and brookedale early next year if you really want a p4

also buying AMD will save you a crapload of money, so buy something else nice for yourself, (more ram, or bigger hard drive) Consider this, it takes a P4 1.7 GHz to beat an AMD 1.33 GHz chip with DDR ram.
then look at the prices, 1.7 GHz is WAY more than 1.33 GHz AMD. Then look at the ram for both platforms, you'll pay out the ass for RDram probably over $150 or more for quality stuff. For AMD with DDRram you'll pay under $100 for the best ram (Crucial PC2400 256 megs is under $90 and will run CAS2)
also do not buy any DDR motherboard without the AMD chipset on them, or else you won't get the full benefit of DDR ram, currently only AMD chipset gives good DDR performance.
I wouldn't get the A7A266 because of the ali magik 1 chipset. It supports both DDR and SDR ram, but when you put in DDR ram you only get SDR performance for the most part.
I strongly suggest any motherboard with the AMD 760 chipset if you want to actually get good DDR performance. I own an Asus A7M266 and the only thing on it that could make me happier would be better front side bus overclocking, and multiplier adjustment. If you don't want to overclock its a very nice very stable board. I used to have an Asus A7V motherboard and my new system with A7M266 and DDR is 10x more stable. My computer very rarely crashes and my uptimes have gone from a day maybe two, up to 3, 4, and 5 days.
And I know that once I stop playing games on the ancient half life engine my computer will probably never crash.
I AGREE WITH THE OTHER GENTLEMEN. IF YOU HAVE A CREDIT CARD, GO TO PRICEWATCH AND CLICK UNDER PC WINDOWS OR WHATEVER OPERATING SYSTEM YOU PREFER. I WAS JUST AT A WEBSITE CALLED PORTATECH, AND THEY HAVE SEVERAL LEVELS OF CONFIGURATIONS AVAILABLE. YOU CAN SPEND HOURS ON PRICEWATCH, SEARCHING FOR COMPONENTS.
