Cpu is fine, what will pull down your performance is the gpu, like in almost every system. That card can play recent games at 1080p on low to med settings. To get upper mid level you at least something along the lines of a GT 760M
laptop counterparts tend to be slower than the desktop one. So you have a 740, considering that a 740 for a desktop is not really that fast, and a laptop counterpart being a tad slower, i would say don't expect much from it.
and since you cannot upgrade anything (almost) on a laptop, by this time next year, you will be at low settings most likely
I dont really have a choice since the seller doesnt even know if the GPU is 64 or 128 bit. I think it would be based on luck then. Hahaha. But anyways, in case i got the 64, is it too much under powered compared to the 128? Are the differences that much?
Oh high sir!! Unfortunately no. As every now and then i go to different places. And i wont purchase it for the sake of gaming and i know alienwares are the molters of gaming on laptops but are way out of the budget. The 64 bit version is halved in terms on membandwidth but are higher in terms of speed i think? And i've read that it is somehow just as good as the 128 bit because of the compensation done on the speed and the memory (the 64 is based on a DDR3 which is better acc to some sources). Also, ive seen someone play battlefield 4 on mid high settings in youtube using the 64 bit and he plays it smoothly with good fps. Since battlefield is on the higher end, i think its good enough for me. Ive also checked game debate .com and the CPU and GPU combination above gets a green star on crysis 3, battlefield 4 meaning its good on mid settings. Hahaha sorry my reply was a novel but please correct any misconception i have
wait wait, when i said 64bit, i am talking about the bus width of the gpu. so with all other things equal, 256 > 128 > 64.
and these days, 64bit is just too slow, its not even worth it if you ask me. as for the ddr3, well ddr5 is better.
