Ah I got it!

Thanks for the tip!
Thanks to all for the opinions
Edit:
I made some calculations, and would like your opinion:
[1] Buy an ASUS P4P800, P4 2.4c, DDR400.
[2] Configure a 800FSB (200*4) 2.4c system, with DDR400 1:1 ratio
[3] Later on, if I feel the need, the need for speed, configure a 1000FSB (250*4) 3.0c system, with DDR400 4:5 ratio
My questions:
(A) (typical question

) What you think? My calculations correct?
(B) The memory ratio is defined in Bios settings right? Which common values are available?
(C) Droping from 1:1 to a 4:5 memory ratio won't drop my system performance? Up to the point of not being usefull making such an overclock?
(D) Uhm ... 1Gb RAM or just 512Mb for now? (with P5 latter this year or Q1 2004, maybe DDR2 will be available, so the longevity of 1Gb is shadowed by new DDR2 memory)
(E) Sticking a little to the topic, do you think I would be able to give it a go at HL2 and DOOM3? (it depends on the graphic card, which you would recomend for this system? GF FX5900?)
Thanks
