my computer has as much as i'll need for the foreseeable future, runs cubase 5 with a multitude of audio, midi, plug ins and effects with no noticeable latency and no processing problems. It has an AMD phenom black edition quad core processor, asus EVO motherboard, 8gb ram, 2TB hard drive, standard HD audio card as I use an external one (novation nio 2/4). I also have a 1gb ati radeon gpu, unnecessary but its nice to have the option of 2 hi def 40 inch screens! I'd recommend my setup to anyone looking to buy a computer that will last a while and not cost the earth. set me back about £650 4 or 5 months ago. The new intel i7 processors look good, but they are prohibitively expensive at the moment, and my amd quad core costs a lot less and certainly does the job. Hope this is useful!
