Take a look at at AT Buyers Guide series. The "Budget" system with a few small upgrades would seem to fit your price range. In general, there's no way you're gonna get "great graphics" on a $650 budget. To give you an idea, very good graphics will run you $175-$200 all by itself. And why on Earth do you need 1GB of RAM?? 512MB should be more than enough for even a mid-range system. Havign said all that, and without knowing a thing about what you plan to do with this system, is:
CPU - AMD AthlonXP 2500+ (Barton) RETAIL - $80
MB - ABit NF7-S (w/ sound + ethernet) - $85
Video Card - Nvidia FX5900 - $180
-or-
Video Card - ATI Radeon 9800Pro - $205
Hard Drive - 80GB WD800JB 7200/8MB - $69
Monitor - NEC AS900 19" - $175
Case/PS - Anything with 300W ATX - $50
Misc - keyboard, mouse, etc. - $50
TOTAL - $689 (Nvidia) / $714 (ATI)
