1st Gen Intel IMac - Will Tiger to Snow Leopard upgrade work?

Question

My IMac dates from late 2006 & was purchased when Apple first started selling the Intel Dual Core machines. Here's my specs:
Model Identifier:    iMac4,1
  Processor Name:    Intel Core Duo
  Processor Speed:    2 GHz
  Number Of Processors:    1
  Total Number Of Cores:    2
  L2 Cache (per processor):    2 MB
  Memory:    2 GB
  Bus Speed:    667 MHz
  Graphics card is an ATI Radeon X1600
  Current Tiger version is 10.4.11
  Disk space not an issue, have > 177 GB available
Snow Leopard supposedly requires only 1 MB of RAM, but I've seen other discussions with commenters recommending 2 MB minimum (kinda took me back to my PC days..."look at the specs on the Microsoft package and double them"). I haven't opened the Snow Leopard package yet, so I can still return it if necessary. So what do the community's experts think...will I be able to do the upgrade without any problems, or am I setting myself up for a world of pain? Thanks in advance to all!

Answer 1

Yes you can, as the great Kappy guy sez, but the Core Duo only supports 32 bit mode, not 64 bit mode. & 10.6.x is as far as you'll ever be able to upgrade it.
Do max the RAM out if it isn't already...
