I hold of on a new system until i can get the performance I desire for about $1200, this generally equates to a system which will last me 3-4 years.
My last system 2 years ago was just under $1200.
Core2duo e6600
2GB DDR2-800 ram
640GB HDD
Geforce 8800 GTS 640MB
Its served me well, I'll probably upgrade next year, or whenever the next generation of graphics cards hit as my 8800 is still capable of handling current-gen games at 1680-1050 resolution.
