Re: Pc buying advice
the best one so far is number 4. it's also a little more expensive then the rest of them.
they all have the same CPU, but what makes number 4 stand out is the GTX 650. it's a little better then the rest of the GPU's the other machines comes with. it has lower RAM capacity though, but in reality you don't need more then 8 if you don't play around with virtual machines and servers.... some high end 3D modeling aplications might benefit a little with more RAM... but i'l rather have that better GTX 650.
if i should choose another one, i'll go for number 3. only due to the (in my view) better looking case.
it's not really better then the second PC.
i am not a fan of the first one, because it doesn't have a dedicated graphics card
