few months ago upgraded 2011 i7 2.0ghz quadcore mbp, replacing optical 128gb ssd , buying 8gb of 1333mhz ram (about $250). upgrade wicked success , mac ran @ blistering pace. couple of weeks ago experienced gpu failure plague 2011 mbp's. bad, mac wouldn't boot , needed work files off of had shell out $250 guy reflow gpu (labour expensive in aus).
understand reflowing isn't permanent solution, i'm running gfxcardstatus , smcfancontrol showing running @ lower temperatures , i've disabled discrete gpu. im still cautious whether fail again did first time , because need work files makes me nervous.
plan running 100% right quite throw on ebay, looking @ sold items mbp same model similar upgrades go between $1000-1500. therefore cut losses on 1 , maybe little added put directly brand new 13" mbp retina 128gb ($1500) benefit increased portability.
way no longer have 1 liability , have last minimum of 3 more years. have 1tb usb 3.0 hard drive use store larger files.
main q's
1 - see significant performance change going ivy bridge i7 quadcore i5 haswell dualcore? dont use graphics intense apps (just logic pro , office)
2 - if continue run current setup discrete gpu disabled , monitoring temp... chances of having relapse? 4yr old technology makes me edgy.
upgrade or not?
dudes
currently you've sandy bridge quad core. ivy bridge mid-2012.
haswell dual-core less powerful.
if continue current setup, it'll still fail, because heat cpu affect gpu's solder joints (they're in same area) , when solder fails, won't boot @ all.
logic pro multithreaded. i'd recommend baseline 15" rmbp instead.
okay, know how battery cycles , work. want know is: how many cycles battery has how old battery is how many mah macbook shipped with how many mah have now reading thread on different site macbook batteries , commenting battery info. of them commenting saying reached 120 cycles per year. 1 guy said mac 3 years old on 250 cycles (avg. 83 year). think person had 400 after 2 years. in 'system information' says age of macbook 3 months old (when arrived said 1 months old, i've had 2 months) , have 98 cycles, using many cycles? i'm asking because realised apple batteries more or less useless @ holding charge after 1000 cycles , if i'm averaging 100 every 2 months gives me 1.7 years until macbook more or less desktop... to me seems poor previous windows laptops owned lasted long , expect lot more machine on £1k. (i have been told batteries in newer macbooks glued in place , replacing battery hard job , cost lots of money, mistake...
i have external monitor (nec pa271w) has custom calibrated profile. problem i'm having whenever i'm on safari , use magic trackpad go previous page colors off while page reloads. once it's loaded colors go custom profile. after lot of reading found out if set system preferences - display - color srgb iec61966-2.1 colors match , page reloads faster. here's example of i'm seeing while go 2 finger gesture. issue happens using coverflow in finder. has experienced same issues on external monitor? driving me crazy Forums Macs Mac Accessories iPhone Mac OS & System Software iPad Apple Watch Notebooks iTunes Apple ID iCloud Desktop Computers Apple Music Professional Applications iPod iWork Apple TV iLife Wireless
