Ok well, if u wait for the next gen CPU, etc. you'll always bein waiting. I say just get a C2D, a good 975X board that OC like mad crazy, 2GB of ram, cheap video card till DX10. Maybe get a nice moniter(s), RAID 2 raptors and have a backup drive, 2 DVD±RW drives if ur into DVD burning (burn 2 DVDs at once with a dual-core and 2 RW drives).
