Basically I want a computer that I can use to capture/edit video, burn bd-hd discs and basically have a system tha'll last me at least another 5-6 years.
Why, is there something I should know about it?
Well, I don't know how much money you have lying around, it's just that this computer is fairly expensive.
For video editing, I can understand some of the choices (i.e. the expensive CPU and lots of DDR3 RAM)... it just seems a bit weird to have such an expensive computer with only a moderate video card, for example (I'm not sure what video card is specifically useful for video editing, or if there is such a thing, though), or only a single hard disk (no RAID; isn't HDD access speed also an issue with video editing? And if you are writing/deleting a lot on the HDD, which I would expect, I would want to have a seperate one for that, and not use the same HDD that has the OS on it or your valuable personal files).
And I would generally question the use of 64bit Vista, though the advantage of having more RAM is surely tempting and probably useful for the video editing at least, since there might still be some incompatibility/driver issues with 64bit Vista, that might become quite a PITA, while currently it offers only a marginal advantage (only the bigger address space, so more RAM can be used; but for most applications 3-4GB are more than enough), since pretty much all software is still 32bit. BTW, is the OS the full price one or the way cheaper System Builder / OEM version? And why "only" Home Premium and not Ultimate?
Also, is the motherboard you get in that computer specified? For that price it should better be among the best available on the market.
Then, McAffee isn't considered one of the best anti-malware solutions, AFAIK (it's no Norton, which should be considerd Malware by itself, but still). I don't know the price tags on some of the other extra services you selected, so it's hard to say anything specific... for example the 1 year online data storage sounds a bit weird to me (unless it's really cheap, like $10 or so)... can't you just get your own webspace and .htacess it for (way more) protected storage space and tons of other possibilities?
All in all, I wouldn't be surprised, if you could get a computer for half the price, that does everything you need, leaving you with another computer in three years for the remaining money, that is about twice as powerful as this one.
Anyways, mostly I'm saying that, before you buy a computer with that price tag, you should really have considered your options and choices and thoroughly thought it through (which you could very well have done already, I cannot say that and am not implying that you did not

).
Bye
Thanee
