Hello, first of all I would like to thank everyone in advance that is going to share their input and their opinion on my situation. I'm a college student, currently a fine arts mayor. Mainly I use Photoshop and the adobe suite. I also sit in, auto cad lectures and love using it. My current laptop is a mid 2010 MBP i5, 8gb ram and 330m. I can use photoshop but lags and it does not handle autocad 3d modeling at all. Its time for an upgrade. As you can imagine I'm kinda on a budget. But its my money maker, so I could justify overdraft on my budget. My question is, rmbp 15' base, plus 16 gb ram upgrade and perhaps cpu (+100) upgrade. Or go full out, sell my soul to a bank and get the dGPU version. Have been trying to comprehend benchmarks and all, but I'm clearly out of my depth. So far what I've gathered, DGPU better for gaming (I do NO gaming), but also good for external display which I would really like. I have a Desktop PC (OC i7 4.0 ghz, 12gb ram, GTX 570) that I'm dying to get rid off. Cant afford the light bill it produces, and the size severely annoys me. Although its great for Cad and Adobe work. My question is could I replace it (the PC) with a base rmbp? or top end rmpb? and get similar performance? Tried the 13' at bestbuy, screen is so small. I'm very visual and I'm a big guy 6 feet, I don't mind lugging around a 15', besides the new retinas are made out of clouds and anti-matter, in comparison to my mid 2010, which is made/compacted out of the core matter of a dying sun/black-hole. My point is, which benchmark should I be looking at? even better what is your suggested model for my needs? Heavy photoshop, amateur autocad. BTW I manage, somehow to be limited by my ram 8gb, so Im really set on 16gb and future proofing. Seems rational, perhaps it not, do to maverick magic ram management. 256gb is fine, but I also read the current cover article in the blog that says the 512gb drive performs best. Although I have a nice external HD that I use to dump all data I don't need. Moreover, I'm also an avid user of drop box and Google drive so the upgrade is painfully expensive, for me at least. BTW, I have friends with render farms and wont be rendering anything monstrous on my laptop. Iris Pro seems legit and I would definitely appreciate not being handicapped by my proximity to a power outlet, this pint seems relevant to me, as it's safe to assume that the dGPU is going to make my laptop power hungry. So what would you get, if you were in my situation? I'm so confused by choice. Also I have a 1500 apple gift card, so I'm limited to apple, and love their products and wouldn't touch a windows laptop with a 10 foot pole, in my younger days I experienced the 1 year cycle of window laptops. Many thanks in advance.
