Hi to all. I'm just about to purchase my first big time interface and software ( Apogee ensemble& pro tool's 10) When checking the spec requirement for both these products I realized that I was gonna need something new to rum them off(bye bye laptop ) and bank account lol. I started off looking at apple and nothing else, as this was the recommended product for these items, When I looked a lil deeper into it I saw that fire wire wasn't as essential as it was made out to be (PCI). I then started looking at HP towers, the price seemed so much better considering all the extra memory these pc's had for alot less money. When checking the spec in detail I saw that the graphic's card (nVidia quadro) upped the price considerably. There were computers with virtually the same spec, when it came to memory and input devices for alot lower price. The only problem being these computer came with AMD graphics cards. Is it totally essential to be running my comp on a Nvidia card?? It just seems to be the only specification that seems a little bit odd to me?
