I just wanted to mention that dual or tripple or N-core doesn't really matter right now,
as Blockland does only support one core. (Most applications only use one core :P)
So the speed of one single core is important, 3ghz for me, if it would support dual cores, well, 6ghz.
I'm just hoping developers will stop producing stuff for dual cores and finally realize that a proper N-core structure is needed.
Well, not fully the fault of the developers, I admit that, the hardware developers are part of the problem too :)
As for the thing with the integrated graphics, that really isn't such a amazing thing, when it comes to integrated graphics there are mostly two kinds of them,
the ones with their own memory, and the ones with shared memory.
If they use shared memory, well, that sucks, as they take up part of your normal ddr, and also have a longer way, resulting in a bigger latency when it comes to internal data transfers, making gpu stuff quite slow.
The ones with dedicated memory, well, are quite fine for blockland, as it doesn't have such big dependencies on the gpu, more on the cpu.
