Power Mac: Buy now or wait?

[Xephian]

Do you think it would be good to buy a Power Mac G5 2.7Ghz with a 6800 GT and a 30" ACD now? Or should I wait for Apple's Paris Expo in September? After hearing about the Power Mac shortages, nVIDIA's new Geforce 7800 GTX, and the new Dual Core PPC 970 FX I am thinking there might be an update for atleast one of these things at the Expo. What are the chances of an update and should I just go ahead and buy this now or wait?

depends on how bad you need it

If you absolutely need it now, I say take the plunge.
However, Stevie J. did said that he had alot of great power pc products in the works at the last keynote. So maybe you should wait it out til the Paris Expo and see what ol' steve has in store for us. The update might be something amazing like dual-core systems or something mundane: same G5's but in five fruity colors.
