So in regards to some large monitors needing graphics cards (according to reviews I read) if I was to go with the following 30" monitor could that be able to be powered by the integrated graphics alone.
Dell Ultrasharp U3011 30" Widescreen LCD Monitor - Midnight Grey [U3011]
As you say the price is high but I have the money to get it, if anything that is why the decision was so difficult, compared to if I did not have the money and I could have ruled it out off the bat.
Also in regards to Corsair possibly not being the best choice, any particular brand of power supply that anyone would recommend because elsewhere Corsair was recommended as one of the good brands of power supplies.
I also looked up about CPU vs GPU encoding, and found a site hat ran several comparisons. One of which was with intel Sandybridge CPUs, (I guess they have had no time to update it yet) and apparently while GPUs can be handy for encoding they are not sufficient to justify buying one purely for that purpose. So assuming the above monitor can run of the integrated graphics, I think I will definitely start without a GPU and see how it goes.
