It all depends on YOUR financial situation and your TRUE needs. Some people will tell you something like, "oh but it has to have this or that will suck." That may have no regards to your typical use. Might be due to a game or specific program that is not compatible in the "best" way for a particular use.
You need to get the MOST MAC you can get and is this $1200 deal the MOST MAC YOU can get for your $1200??? Isn't that the true question? So, let's lay it out RIGHT HERE.
1 - Will this Used MBP be what YOU need it to be?
2 - if not, how much more is needed to bring it up to what you need?
3 - if so, is there overkill?
4 - will the new highly anticipated MacBooks + MBP + MBA fill your needs BETTER???
5 - CAN YOU WAIT??? Can you wait??? Can YOU wait? I WOULD!
Graphics Card is probably a mute point. Unless you are a big time gamer OR you use graphics intensive programs like PhotoShop, the graphics card in the MBP is OVERKILL. And that nearly adds $500 to the current base price of the $1999 model 15-inch versus the $2499 model 15-inch. BUT if the graphics card is the major feature for you, PERHAPS you should WAIT til the new lineup is released and get a KILLER deal on a reconditioned MBP.
Or, perhaps the new MB line will have ALL of the features you care about for $1199 or even possibly $999. It seems imminent and evident that we are going to see MacBooks made from aluminum looking similar to the current MBP or MBA. AND, the new MacBooks may have a dedicated graphics card or something more substantial than the prior MacBooks which had a shared memory graphics card.
So, you want it for simply because YOU, I repeat YOU have to have it NOW, it is really an object taking up every second of your time. Then, perhaps you should go down the street and bargain negotiate your way into the best deal and buy the darn thing.
I know from experience that I ALWAYS wish I would have waited on EVERYTHING except the iPhone. I bought the original on the first day and have not ever looked back. USUALLY, I am wrong though, like the day I HAD to have a darn MBA that day. I bought one. And I ate about $400 three months later because of it. I never used it I only thought/wished I had to have it.
Had I waited, to now, having learned around a month ago, that the NEW MacBook lineup will be out around October 14th, I would have benefited. Because I would have purchased based on my TRUE needs over true HAVE to have revelations that are usually not at all NEEDS.
Going back, you have $1200 cash and you HAVE to have this MBP TODAY. Go beat down the door and buy your MBP with Dignity and Honor. For no MacBook purchase is a poor decision, as timing reveals all in the end. Only the mere grasp of a MacBook could throw off otherwise perfect rationalism.
I need to get back to waiting for the new MacBook lineup. Can it be true? A new MacBook that is in aluminum, AND has a dedicated graphics card, and that is ALL I need. I don't need the 15" but usually stuck on graphics card for web design stuff. However, I would sure love even a 128 MB dedicated graphics card in the new 13.3-inch ALUMINUM MacBook.
Best wishes with your WAIT versus buy now dilemma. It is such a sad but true dilemma. There are so many of us afflicted with our sorrowed MacBook stories.
Be well.
