CPU should be at least i7, 12 GB memoty, intel graphics card with CUDA capability, at least 3 internal hard drives to start.
I'm sure sombody else will chime in with additional suggestions.
Now Dharma from Adobe Online Support answer me that Premier Pro CS5 and After Effects CS5 are both doesn't support 32-bit operation systems!
So all I can do is reinstall my Windows 8 to 64-bit version or use CS4 versions of AE and Pr.
Ever since Premiere Pro cs5 you have had to have a 64-bit OS. No way around this that I know of. Your specs are for sure lower than ideal, however if your OS was 64-bit you would actually be able to run the software editing HD footage just wouldn't be a very good experience.
Core i7 is not a necessity, I'm rocking an i5 2500k and mowing over any video that comes my way. For HD editing, the biggest thing is to get at least a modern 4 core processor; ie i7s & i5 of the 2000 and 3000 nomenclatures.
Also, Peru Bob, I think you meant Nvidia graphics cards, as those are whats needed for CUDA and MPE hardware Acceleration. One needs at GTX card with at least at 1GB video memory. I'm afraid that olegb0nd's ATI Radeon HD 6570 won't help much with Premiere, however it is better than no dedicated GPU at all for most computing needs.
Lastly, while 3 internal drives are preferred for editng systems, one can get by very well with 2. One for system and applications and a second large 7200rpm drive dedicated for editing. We have 4 Premiere systems set up at our shop in this manner, and mine at home only has one editing drive as well.
I agree that 12gb is a more realistic minimum than Adobe's recommended minimum. We use 12gb on two of our systems and Premiere uses every bit of it. I use 16gb on two systems and it gives me a bit more headroom. I have't used CS 5x or 6x with 8gb so I really can't say for sure how it handles HD editing, but if every bit of 12gb is used....
The core i3 is going to be a big drawback for HD editing. AVCHD and H.264 source material will choke the machine.
Good luck olegb0nd, but this machine (laptop?) is not spec'd for HD editing, and may only be good for DV video. You might be able to get workable performance if you convert AVCHD and H.264 source material to an intermediate mpeg 2 based HD codec before editing, as that is a lot easier on the CPU than AVCHD and H.264.
