I noticed in your signature you went from a '09 C2D 2.8 to the new April/10 i5 - do you notice much difference between the two? Happy with the upgrade?

Thanks.

Honestly they seemed to be about the same. At work we have quite a few 2.8's sitting around so I did some tests with them sitting side by side.

2.8 seems to open and do, simple, quick tasks faster.
open iphoto, Firefox, little quick things.

but my i5 started pulling ahead when I would throw open AE, PS (anything Adobe) had multiple things open, etc.

when the 2.8 would win, it would be by half a second. the i5 would takes 10 seconds at a time off some of the upper tier things.

GPU wise I know that I have a better one, but less vram.. dunno what to think there.

It may appear equally fast opening windows and the like but where the difference really shows up is opening big Keynote presentations or downloading lots of e-mails, anything truly processor intensive literally screams. :cool:
 
btw its bad for a lithium battery to completly drain the battery to 0%...
You should never go below 10%... under, the battery take "damages" and loose more longevity than normal...

That's complete nonsense! You have to drain the battery completely to calibrate it, which should be done every 30-60 days.

well that is what apple is saying... Being into RC hobby for quite a while (Helicopters and planes) all heli's and planes have Lithium polymer batteries, and they actually never should be discharged more than 10%. This is a big "no-no" in the hobby.

not sure what to make of it all though... i mean i do not discharge my RC batteries beyond 15% max, but just yesterday I calibrated my macbook battery and discharged to beyond 0%...

ps, logging battry time now, using Ibatt2 after the calibration, but it still sucks and can get NO more then 3 hours of work out of it. I will be visiting a repair shop..

Notebook batteries are quite different from those used in hobby planes.
