No matter what your other components are... your RAM must be more than 4gb. Im suffering from having a 2gb ram system. Once my layers are more than 15.. it has already reached 90% of ram usage. i was like.. OMG!!! Secondly, a mid end graphic card will be sufficient. No need high end graphic card. Or you may choose a workstation GC. up to you..
low-end is sufficient. like the HD3450 which I just reviewed recently. used it to edit a bunch of RAWs, no issue.
about the layers part, your post is misleading. it lags the system not because of # of layers but what you have on each layer. i have plenty of files that come to around 100 layers, no problem with it. dimension is 600x400 only. on the other hand when i do buntings and stuff, less than 20 layers but 6ft x 2ft @ 150dpi or higher, then yes - it's laggy already.
so if you're putting your FULL image size on soooooooo many layers, it's no wonder you're suffering.

you need to do it smarter.
btw i work as a web designer and i also post process photos. I've done them on 2GB system and never found it to be an issue, even when opening mass RAW files. i donno, maybe it depends on what you're expecting la.
so far only 1 person mention HDD space (base on what i read) - seriously, HDD space is really great for applications like photoshop. notice how it slows down when lacking HDD space. I'd say, get an RM 400 - 600 processor would be fine, more than powerful enough for PPing purpose. 2GB RAM also enough, put 4GB if you want cos heck, RAM nowadays so cheap.

(I'm on 4GB now, i don't find it any much diff from 2GB........ of course it shows 3.25GB la) . i think most of your $$$ should be on HDD. 2x 320GB perhaps?

When using your PC for a photo processor and all, do not stinge on a LCD monitor and budget in a monitor calibrator. For LCD monitors, get the S-PVA or the S-IPS type and not the TN type.
easy for us to say.

I like S-IPS LCD, i'm using one and loving it.
I also have TN panel LCD and i think it's really fine to post-process on that one, it's not that crappy as how many has described it - just that it's not S-IPS quality.
it really depends on the person and how picky they are. not everyone can afford to get high-grade LCDs. ask our photographers, here, how many of them actually have S-IPS panel LCD?
