It's gotten kind of confusing lately. Here's how it works.1. PC133 runs at 133MHZ as long as the Chipset on the board supports it and the CPU supports it. AMD, VIA and ALi all make 133 MHz chipsets for the Thunderbird.
2. Don't buy an Athlon, Buy a Thunderbird. Don't buy a Slot A motherboard, buy a Socket A board. For a P3, don't buy a slot1 buy a socket 370 board.
3. Next, you need to make sure you get a CPU that has a 133MHZ FSB. For example, the 800MHZ P3 has two models, a 100MHZ and a 133MHZ FSB version. I think all Thunderbirds support a 133MHZ FSB.
4. DDR- this requires DDR ram and a DDR motherboard. Your only real option for a CPU is a Thunderbird. The designations are different from SDRAM but basically 200MHZ DDR ram is actually 100MHZ ram that allows read/writes on both the rising and falling edges of the clock pulse. Standard ram only works on the rising edge of the clock pulse. it's the same theory for 266MHZ DDR.
There are still some issues with the drivers on the DDR motherboards so they don't give much of a performance increase over the 133MHZ FSB boards (Yet).
If you current computer works well, I'd wait 2-3 more months. By then the driver issues on the DDR boards will have been settled, the price on the DDR MB's and ram will have fallen. The SSE enabled AMD chips should (can't say will) be out. You'll have more money saved for your system, and the video card prices will have dropped further.
Between now and then you could get any of the following items you may need:
Hard drives, floppy drives, CD-Rom drives, keyboard, mouse, monitor, modem, and sound card.
One of the reasons for the slump in PC sales is those that want newer hardware know the technology will step to a new level in the next 3 months. By the end of a year, DDR ram will be cheaper than SDRam. So next year it will cost more to add memory to a sytem using SDRam than DDR memory.
