Which Pre built desktop is better?

[Guest]

I'm going to invest in a new desktop, it has to be pre built because I don't have the time and experience to put together a custom build. I mainly use it for video editing/rendering using vegas. I do light gaming like minecraft Need for speed etc. I have a budget of about £800 but the two options I have are

So my question is which one is better and is the second one worth the extra money? Finally, which one will be faster and better for my needs, and which graphics card is better on either machines?
Many thanks, Josh

They are pretty similar PCs, with same CPU. I dont think the 2nd one is worth money, but you might need 16GB of RAM since u work video editing. Anyway,
Are you sure you are not able to make a custom build? You really can make it way better, for your needs. It really isnt science fiction, and Im sure you can find help on this forum, or even already custom builds of someone else that will suit your needs
