Thanks 2 cores made a load of difference! The graphics still seem a bit sluggish, in the device manager it says it's using a vmware SVGA 3D adapter, is that the best I'll be able to use, there is no way I can utilise my NVIDIA card?
Should the vm using the above settings run as smooth as it would on a full install on a pc with the same specs? As it'll be for development I'd need to know if its the app being slow or just the OS! Cheers.
