The battery at min brightness and wifi off movie powe saver mode crosses 4 hours 20 minutes for me using headphones
The 510p has changed to 768p screen or an upgrade to 900p which I doubt will be in India if the 510p does make it here
The 750m is exactly a overclocked gimmick of a 650m. 3dmark around p2700. I overclocked my 650 to over p3200 and game on 1100 regularly without throttling though I find 1000mhz to be the sweet spot which is still higher than the max 750m boost. Point being both the chips are the same. You can choose to set it at whatever clocks you want and get the corresponding performance. The 750m has a max boost to 960 MHz as shown online… not to mention I read that the new 750m models are more prone to overheating due to higher clocks and poorer thermal paste
Can anyone try the bios mod and report it here lol I don't feel like experimenting
although afaik it would enable an option between sli and Optimus
