I've not found it has had any problems with running programs at all. Have had to download 64 bit versions of some software.
Nothing that's a show stopper, its just feels that it is not yet a fully rounded product.
Had major problems with getting the Lacie Firewire 800 card to work on my external drives and have to use USB2.0 or Firewire 400 (tried all the registry fixes recommended for Firewire 800 for 32 bit OS. Lacie support was no help - they said try another brand of card!!)
The RAM was a bit of a disappointment when I found out that each programme can only use up to 3GB (I put in 8 GB hoping for great things).
But it has its advantages with a dual processor: the other day I had PTGUI stitching a 300 Mega pixel image in the background (it can take ages), whilst using CS3 to edit another large image and I had Lightroom open and was surfing the net (two screens are handy!). System just kept working and had a RAM usage of nearly 5GB. Nice !
Would I go 64 bit if I knew what I know now.....probably!
