Hi guys, this is my first time posting in this forum. hope I don't make mistakes that upset you. Sorry also for my bad English since I am not a native English speaker.. I am currently thinking to buy 2nd hand rMbp 15". Please give your opinion on which one I should choose. Thanks lot for the comment and help! Background I am using my laptop mainly for watching movies, web-browsing and remote desktop for working. I am a casual gamer who only play MMORPG GW2, LOL, Dota2 recently. I just started to do a simple video editing for my gopro footage using normal GoPro Studio software (not really an expert in video editing, just started to learn ) but not sure in the future if I am going to use more heavy or advance software. I am currently using HP Pavilion dv6-7090sf laptop for web browsing and watching movies (http://www.notebookcheck.net/HP-Pavilion-dv6-7090sf.75532.0.html) and iMac mid 2011 - 2.5Ghz i5 core (with AMD Radeon HD 6750M 512MB) for playing GW2 and video editing. rMbp Choice 1. rMbp 15" mid 2012 - 820 usd - 2.3 Ghz i7 core 3rd generation (Ivy Bridge) - 8Gb RAM 1600MHz - 256Gb SSD (sata III) - Intel Hd4000 + GT650M 1Gb - Excellent exterior but with no warranty left 2. rMbP 15" late 2013 - 1050 USD - 2.0GhZ i7 core 4th generation (Haswell) - 8GB RAM 1600MHz - 256GB SSD (PCIe-based) - Intel Iris Pro 5200 - Excellent exterior and with warranty until Nov 2016 My Analysis and Questions The good of mid 2012: 1. GT650M - I believe this dGPU is better compared to Iris Pro 5200. But is it worth it buy the older model because of this? I read about Iris Pro 5200 review and some people said it is quite good for daily use. Any idea if I can play GW2 in native resolution using Iris Pro 5200? low quality maybe? how bout for normal video editing, is Iris Pro 5200 good enough? My thought is although GT650M is better than Iris Pro 5200 but GT650M is also not a powerful GPU and cannot play high quality 2014/2015 games anyway so why bother to buy older model for GT650M. I am currently using laptop with GT630M and iMac with 6750M dGPU, will I be disappointed if my rMbp only using iGPU? how is the performance between Iris Pro 5200 vs GT630M/HD6750M? this is one of the comparison from game debate but the result is so confusing (http://www.game-debate.com/gpu/inde...s-pro-graphics-5200-mobile-vs-geforce-gt-630m). Individual category looks GT630M wins but the conclusion saying Iris Pro 5200 wins.. Can someone help me on this? The good of late 2013: 1. Thunderbolt 2 - I am currently not using any peripherals that have TB connection so I dont think it will be matter for me although ability to connect to 4K display maybe be good for the future. 2. Wifi 802.11/ac - My wifi router at home is still using g or n version so even I have wifi ac laptop I wont see the impact, correct? but I think it is a good thing to have for future technology. any comments? is real life speed for ac is really much faster than g/n? 3. SSD PCIe - anyone can comment on the real life speed increase for PCIe compared to SATA connection which is in mid 2012? will PCIe improve boot up time? the main reason for me buying late 2013 will be this point and two points below. 4. Warranty - always a good thing to have and it is more than normal 1 year apple warranty. 5. higher resell value - i believe late 2013 will be in higher resell value compared to mid 2012. In addition, late 2013 also has a little bit of warranty left on it.. please correct me if I am wrong. Sorry if it is a lengthy post. Appreciate all of the comments and help! thank you!!
