CS4 sys requirements

[iMe]

Hi I have a 2008 20 inch iMac with an ATI Radeon XT and I need to be able to run CS4 web premium I just need to know if I will be compatible. NOTE: If I need to I will upgrade my RAM and/or my HD (and If I do upgrade the new HD will be 1.5 TB ) Also If I need to I do have a first generation MBP and I will upgrade it to 1.0 GB of RAM here are my specs:
iMac:
1.0 GB of RAM,
2.4 GHz intel core 2 duo,
2400 XT graphics,
20 inch monitor,
250 GB HD (ugh),
OS X Leopard
MacBook Pro:
512 MB of RAM,(what the heck!!)
2.0 GHz intel core duo, PS: is it 64 bit?
ATI radeon X1600,
15.4 inch monitor,
70 GB HD
Mac OS X Tiger

What graphics Is better for CS4 because if the laptop is better I will upgrade it to one GB of RAM so what one should I use? So what mac would you use people?
Or will both run CS4? (PS: I AM GOING TO UPGRADE THER AM TO 2 GB)

I run it ok on my 13inch mbp 2.26gz and 2gb of ram. I did upgrade my HD to 500gb 7200rpm and also going to upgrade to 4gb of ram. Then I should be fine. But if I can run it with no problems you could probably on your imac.
