Thanks guys. I'm looking at the 13-inch MacBook Pro with Retina Display. Just checked Intel Iris Graphics. Although it's integrated, not dedicated unlike Iris Pro, I got sold to it from this review online (pasted below), mentioning the applications I'll be using, as I've much concern with how well it could handle 3D programs: Autodesk Maya/Max/Invent/CAD as well as Ae, etc..
Iris and Iris Pro GPUs support advanced APIs, including DirectX 11.1, OpenCL, and OpenGL 4.0. DirectX 11.1 is very important for delivering all the best visual effects in modern games. Photo- and video-editing programs, such as Adobe’s Photoshop and Sony’s Vegas Pro, use OpenCL to tap a graphics processor so they can render images faster. And engineering, design, modeling, and animation programs such as Autodesk’s 3DS Max rely on OpenGL to talk to the GPU.

I have decided to wait a little longer to save up for a more powerful mac (MacBook Pro or iMac). In the meantime, I'll be upgrading this little MacBook I'm using now to the latest OS X (from 10.4.11) and see how it handles Photoshop CC, etc, and how well I can adjust to macs, as I've always been a windows user. I checked Refurbished Macs which is a really good idea--wallet-friendly, however, I'm not too keen on it since it doesn't say "Certified Apple" Refurbished Macs as it is presented in the US apple store. We'll see.. (last time I was thinking I'll just get an iMac..)
Thanks again!
