What questions should i ask the manufacturer for this?; • Intel® Core™ i7-4770 3.4GHz QUAD Core Haswell Processor

I have so many questions and any help would be GREATLY appreciated. Ok i know the graphics card isnt good but is this a good pc? i have never heard of the zoostorm make so i am unsure about purchasing it, i have read they can use cheap parts eg the make of the ram/HD the fan. Does anyone no if this is true and does it matter if the Ram for eg is a cheap make because it still sez its16g just like a good make will say 16g? is the NVidia GT640 2GB Graphics Card dedicated and HD? is does not say, if not can i upgrade it to HD/dedicated is DDR3 1333 RAM good? Is there anything i should ask about and havnt? im totally clueless thxI tend to avoid Zoostorm as a brand as they usually use a cheap, low end power supply which not only won't be reliable but will prevent you upgrading components such as the graphics card without swapping the PSU as well. Zoostorm are, if I recall correctly, Ebuyer's "home brand". Nothing particularly wrong with them for cheap home or office machines, but they're not always the last word in reliability, PERFORMANCE, or indeed value for money.

The GT 640 is a dedicated, low end card. Not sure what you mean when you say "HD? is does not say, if not can i upgrade it to HD/dedicated" - if you mean is the card capable of HD resolutions, yes, graphics cards have been capable of this for over a decade -in fact before HD was even a marketing buzzword - so no WORRIES there.
What's your budget for the PC? For £700 I'm pretty sure you can do better than that, if you let us know how much you want to spend we may be able to recommend something more suited for your needs.
