Firstly you don't need to put every single spec down, especially things it doesn't have. Secondly should this be in the games section?
Yes this is a good spec for a computer, and there's no games at the moment that this won't be able to play with decent graphics, and almost none that you won't be able to play at full. In all a very powerful system, that has pretty much the best of everything, short of monstrously expensive graphics cards that aren't worth it. And PC6400 Ram instead of PC8500, but you won't notice the difference. Make sure you get a 64-bit operating system or you'll only see 3 of those 4GB. All in all this is a very fast computer that is reasonably well priced.
However I feel inclined to tell you that your budget is probably too high, and that when you go over about £750 you tend to get a bit ripped off. Aim for the same processor and just one 8800GT and you could save about £250, and only notice about 7-8fps difference.
I would also suggest perhaps building one for yourself with this kind of money. I could build this system for about £850, although you have to be clever where you buy from. I also believe there's a bit too much one-upmanship in the technology that there's no need for: a 19" screen is still massive and another way to save money. But don't build your own unless you know what your doing. If something goes wrong you have saved nothing and no-one can bail you out.
One last thing is i think this is a cyberpower system? I was turned off them due to dodgy customer reviews, just check it out before you commit more than £1000
