Is an Antec Earthwatts 650W PSU enough to handle this system

My current system is:

Core 2 Duo E8500 @ stock speed (didn't use thermal grease = no overclock... oops xD)
XFX 9800GTX+ OC Superclocked to 800 MHz
2.5 Gigs Crucial Ballistix RAM
1 DVD Rom drive
3 120 MM Fans
And of course a hard drive.... 1.5 TB <.<

If I slap a GTX 295 in this sucker, is my current PSU going to be able to deal with it, no worries? I heard the the power requirements were based on i7 builds. Finally, (if) I put it in, could I consider this rig to be.... kickass :p ?
