See, this is why I'm asking for help.
1) Why should I go for a bigger PS? What's the benefit?
A bigger power supply allows you to run more components and/or overclock harder. IMO, the one you've chosen is perfectly sufficient - but there are calculators on the net to work out how big you need if you're worried.
2) I'm not sticking to a certain type of manufacturer, that's just a coincidence, but, better HD, got it. Suggestions as to make/model?
I got a Samsung spintronic F3 which had some good reviews for speed (and a separate 2TB 5400 drive for data storage). Whether that's best for you, though, I don't know.
3) Should I have more than one video card, and why? I'm only planning on having one screen...?
It's a way of getting faster graphic processing. You can cross-connect two video cards if you have a suitable motherboard so you can parallel process your graphics. In my opinion, this just isn't cost effective, though. Acording to online reviews, you don't get that much added boost - and the two cards and special motherboard and larger power supply add up.
If you are sure it'll be cheaper go ahead. When I did this, I found the Amazon was a lot cheaper than PC World and had better products.
I generally use "Tom's hardware" for advice. In my opinion, you're going overboard on your processor and memory. That processor was reviewed as possibly the most powerful out there and you're not going to see much benefit over a couple of steps down. Also, I can't check newegg at work and I'm not sure if that memory is 1 stick or 2. They're often sold in pairs as most memory is dual channel and I'd be suprised if that board had 8 memory slots availible. Are you planning on overclocking your system? If not, you can save quite a bit by using less high end components.
