Some advice on new P.C for Dolphin emu - sandybridge

[LordBarker]

Hi all,
I know there are a lot of threads on this topic, but have narrowed my P.C choice down to the following 3 systems for a gaming rig and Dolphin emu machine. I am going pre/custom built - rather than self-built, due to inexperience. I'm obviously aiming for maximum Dolphin performace.

The choices I have are:

System 1:From Palicomp - apologies for caps - taken straight fom site.

I'm leaning towards the Sandybridge powered machines, but wondered if anyone might add their 2 cents into the mix.
