Best Athlon, PIII, Celeron configuratio

Any ideas on the best CPU/m’board/video/sound/memory? I’m building a new system for home and will probably end up getting a processor running at about 700Mhz (or thereabouts). Budget is tight (I’m using my tax return).

Performance-wise, I’d like to get the best combination available based on whichever CPU I get. I can probably afford all but the latest and greatest in video and sound.

Thx

PS: I will be running work related apps and I play games online …. a lot 😉
