Ok. I've really been avoiding making this choice for quite a while, and I'm sure if you check my back posts, you'll find half a dozen stupid questions along these lines. But this it! This is the time I finally make up my mind! I love my Cube more than any computer I've ever owned, but I'm completely fed up with its slow 500Mhz processor. The time has come for an upgrade. Now, the most I'm willing to spend is the price of a stock Mac Mini - $499. Why that? Well, for one I consider the Mini to be the Cube's nemesis, and also, because that's all the money I have. OWC is having a special (through Cubeowner.com) where they're offering the Dual-1.7Ghz G4 Powerlogix upgrade for $495, which is really a helluva deal. Thing is, I don't know if maybe I should go for a processor upgrade that uses the 7457 chip, which has a L3 cache. The dual-1.3Ghz '57 upgrade is over $600, so that's out of the question, but I know there's a few single processor ones like the single 1.4Ghz at $399. Would I feel that much of a difference between the single and dual, especially if the single had a 2MB L3 cache versus no L3 on the Dual-1.7's? I use my machine for usually light word processing and browsing, but now that I don't have access to my dad's G5 anymore, I've been really using it for a lot of video encoding. Toast encoding one DVD can take over 30 hours right now... So. Given that, which upgrade will be better for me. Oh yeah, and I'll soon be doing a lot of work in SPSS and STATA, so I guess if you've used either program, lemme know how you feel this would affect performance. Thanks for any help, and sorry for putting up another rambling, slightly-incoherent post!
