If you get a 2.4c (800mhz) cpu and use it on a 533mhz board (133 fsb) you would get... 11 x 133 = 1463mhz cpu. You would have to o/c it to get close to 2.4 ghz but you wouldn't get HT to work on the board.
If anything, get a i865 or i875 board and use your current cpu and save to get a new processor provided you have DDR memory.
I'd say don't worry about HT and just be happy with your current setup. If you really have the upgrade bug, a new motherboard would be first to upgrade. The newer i865/i875 boards will support your current processor and memory. Then when you're ready to upgrade your cpu, you can.
If you're a gamer, you might want to upgrade your video card before anything else.
I don't think you should have to wait for everything. I agree that a new 865PE or 875 would boost your performance considerably, as new chipsets almost certainly do. It should give you more overclocking options as well, as long as you don't buy an intel board.
Asus and Abit are currently the best 865/875 boards available. You can get a P4P800 and a 2.4c or 2.6c for under $300. The AI7 is the newest board from Abit. The P4C800, IS-7 and IC-7 are good choices too. You'll have to look at the features of each board and see if you want/need all the extras or just a bare board.
I should mention that some(all?) of the Abit owners have issues with the onboard cpu temp sensor. It seems to read really high. That and a few other minor issues with Abit steered me toward the P4P800 Deluxe because I wanted the ICH5R (raid on the southbridge, bypassing the PCI bus) with SATA drives.
Some of the Abit guys put a separate temp probe on the hs to find the real temp. They found out that the onboard temp sensor is usually 10°C higher. I've read that it's anywhere from 3°C to 15°C higher but the 10°C is the average.
I figured out how to fix my dilemma; i sprung the $230 for the 3.06 533fsb w/HT. now i don't have to upgrade my mobo (which i have only used for about a week), and I still get the HT. thanks everyone for the ideas, the asus board still maybe next though.
Ouch! You should've just gotten a new motherboard and save yourself a few bucks. You probably could've sold your 1 week old motherboard and put that (along with the money you saved) into a 2.4c and some pc3200 memory and get over 3.0ghz and much better performance with the higher fsb. Live and learn.
i didn't know you could get that kind of performance out of that cpu. (groan to self) oh well I wanted to see what I could get the 3+ghz up to with a stable oc. i can't seem to find it on the lists anywhere. on the plus side though, locally, even a used 3+ghz is gold ($300+). so i'll probably just tweek it a little, see what it can handle, then make a profit. no loss here
Bad move Modder. I have the P4T which is a 533 fsb board and it also has HT enabled..I used a 2.53 ith 533 fsb for a long time and got a 3.0 800 fsb and tossed it in..Even without the dual chan mem of the 875 chipset i was amazed with the difference the 800 fsb makes.you would have gotten better performance with the 800 fsb chip..just manually use 200 fps in bios and get the pc 3200 mem an off you go..I would guess some games load 50% faster over 533 fpb.
