At 333mhz FSB (and thus 3.0 GHz), I'm at about 46C right now. Can I go up to 50C or is that too hot under no load.
what cooling setup are you using? what case? you're looking at one part of the equation when you look at overclocking. if you improve your cooling setup, you'll get cooler temps (and possibly lower noise if that's important to you). those cooler temps may allow you to overclock even more.
also, using the bios hardware monitor gives wildly varying results. in my abit ab9 pro, the bios cpu temperature usually is lower than the cpu's temperature if you use a program like coretemp. the bios might say the cpu temp is 46 but it is really 55 for example. i haven't got coretemp to work invista, but speedfan does work. but speedfan doesn't work with all mobos. inmy case, it works fine with an nfm2-nview but not the abit ab9 pro.
anyway, if possible find a tool to get the actual cpu temperature. try coretemp or speedfan. if running xp, coretemp should definitely work.
anyway, for a reference point as to how different cooling setups can impact the same processor with the same mobo, in a P180 case, my stock E6600 idles at 30 and peaks at 50 under load -- and i'm passively cooling it with a scythe ninja heatsink. my ambient temp is about 22.
in my htpc case (antec take 4 rackmount), a different E6600 at stock idles at 36 and peaks at 55 under load, using a zalman 9500. i'm going to switch up the cooling approach there because the zalman is too noisy for my taste and isn't doing a great job.
basically i think the best strategy is probably optimizing your cooling setup, then worrying about how far you can push the chip.
