Yo Yo Yo! I've been out of the country all summer, so I missed all the MWNY fun. Reading over the forums, it looks like things were pretty cool. Alright, on to the question. I'm upgrading my Cube 450 with one of the PowerLogix upgrades. I can't decide which one I should get, though. The 1 GHz chip is $799 and the 800 MHz chip is $599. I'm wondering if the extra 200 MHz is worth an extra $200. Just in case you're wondering, I'll list system specs below so you'll get a little better idea what I'm working with. G4 Cube 450 (To Be Upgraded), 1.5 GB RAM, 40 GB HDD, GeForce3, and I will be upgrading to Jaguar. Hope that helps, folks. Any input that you guys could provide would be great. Thanks!
