Unless you are wanting a Mac, I would recommend a PC for CS4 at this point.

Although it was suggested that you need a powerful video card in a prior post, this is not really the case. Although CS4 is the first version of PS for the PC that will take advantage of some of the capabilities of a video card (i.e. – rotating on the fly, smooth zoom) these functions are more ‘Gee whiz’ than necessary (we lived w/o them up ’til this version) and they are not needed/used by filters etc. The real crunching that happens in PS is on the CPU…

And this is why: The Windows version of CS4 supports 64 bit Vista, there is not 64 bit support for the Mac. And yes Virginia, it makes a significant difference.

Example: Alien Skin Blow 2 filter/Add-in supports 64 bit. I had a need to blow up some of my images significantly, such that the resulting files were more than 3 GB. Running such a process on an HP Pavillion with 32 bit XP with 2 GB RAM would take appox. 35-45 minutes. I recently purchased a never Pavilion with 64 bit Vista and 4 GB RAM (and by the way shared video RAM – something you would think less than ideal, this is a HP DV7-1232). My ‘blow up’ time was reduced to 7 minutes for the same 3 GB file.

The cool thing about the 64 bit Pavilions is that they support up to 8 GB.

Do the Pavilion.

Did I mention you can get them at Staples on sale (every other week) for $650? (At the price you can use it for a year and next year get the Quad core version for the same price!)

HP,Dell,Microsoft computer can help you.For greater efficency in Photoshop CS4 try Vista or the upcoming Windows 7

just buy a PC that meet the system requirements of the photoshop

ok,, just buy a PC that meet the system requirements of the photoshop,, better have high video card.. because price versus quality

Best computer would be HP Pavillion, could take in more space than those other computers such as the Mac and the older PCs
