Delll 9300

I'd also say hard drive speed will help, because PT and PostgreSQL write to it a LOT. I'm glad I got the 7200rpm on my 9300, because it literally flies with PAHUD and PT running - there's not even a delay, maybe the slightest flicker when it updates between hands.

I think RAM helps a little but I've just got the stock 512Mb, and it runs fine with that.

PS I'd also use Partition Magic, and use a different partition solely for the database. This way you can also use something like Diskeeper and keep it defragged regularly, plus running at top performance. At least - that's what I did.
