Hello, I'm trying to figure out which type of computer to buy. Currently I own a three year old 17" Macbook Pro which works pretty well for the type of work I do which mainly consists of graphics design, 3D molding and film making. However when running multiple applications of these types such as Final Cut Pro and Photoshop, my MBP will begin to run quite sluggishly and that seriously slows down my workflow. So basically I'm looking for a powerful computer that can handle these tasks. I'd like to get another Mac since I've been impressed with their service, the appearance of their computers and Mac OS X but can't help but notice PCs with comparable and even better specs going for less money. Especially if you custom build your PC. I considered a 27" iMac but my understanding of those is they use laptop parts. The Mac Pro would probably do, but they seem way overpriced for the specs they offer. I tried building a PC online with the exact same specs as this Mac Pro and it came out nearly $800 less. My question then would be if higher end Macs are worth the money for power users. Obviously they cost more so what do you get for your money other than the nicer case? Thanks for any advice you may have!
