I am looking at buying a new computer and i have a choice between "8GB [4GB x 2] 1333MHz DDR3 SDRAM [Laptop Memory] Corsair or Major Brand" and "GB [8GB x 1] 1600MHz DDR3 SDRAM [Laptop Memory] G.SKILL" for the same price.

I see the second had more mhz but is 8gb x 1 vs the 4gb x 2 and is also a lesser brand. Which will give better performance?

Stick with the least amount of sticks so you can upgrade latter. It can be hard to resell the smaller ones. I am guessing your board is two channel, so two is all you need. Adding for sticks does not increase performance. If you can get 1600mhz Corsair in the series you can afford. Its the sweet spot.

Duall channel 1333 (2x1333 Mhz sticks) will be faster than single channel 1600 Mhz (especially if there is onboard graphics like AMD's APUs or HD graphics from Intel). However, if you have the choice, get 2x4GB for the laptop to get the fastest performance that way. However, if you will upgrade later on and get 1x8GB 1600 Mhz, you can always toss in another 1600 Mhz stick to get that dual channel performance.

As for brands, there isn't much of a difference between similarly rated RAM these days, especially for laptops. Neither G.Skill or Corsair have their own fabs to produce memory silicon, so it is all just sourced from somewhere else, and frequently, multiple brands will actually share the same physical memory die on the sticks.

G Skill is by no means a lesser brand. In a desktop you typically want to have two sticks, however in a laptop it won't really matter. Also, going from 1333 MHz to 1600 MHz is minimal at best in a performance gain. Personally I would go with the two sticks. What is the CPU? There are certain AMD processors that speed really plays a big role in.

The processor is a Intel® Core™ i7-4700MQ Mobile Processor and i am deciding between 2.4ghz and 2.7ghz... your opinion on that would be appreciated too! its $150 difference. and if I am unsure if i will upgrade laptop as I do have a decent gaming pc that i plan on using most of the time. laptop is more of a school stuff with some gaming potential for those mobile situations lol

if u meant graphics... NVIDIA GeForce GTX 765M 2GB GDDR5 Video w/ NVIDIA Optimus lol

For what it's worth, i7-4700MQ Mobile Processor does support dual channel, so you'd pick up a boost performance wise, and basically 8GB should be plenty for the lifespan of a laptop - typically 2 years or less. As far as GSkill, it's the top DRAM manufacturer out there right now, many laptop dealers have deals with some of the manufacturers and try to pass them as a MAJOR BRAND to keep them happy, it is somewhat telling though that they advertise as 'CORSAIR or a Major Brand' you could end up getting with basically a no-name brand that they might consider or say they consider a 'major brand', I for one don't like iffy advertising like this, I would want to KNOW what I was getting, especially if this might mean, RMAing, and shipping, having your money tied up for a couple of months if you get and don't like their 'major brand'

so are you suggesting the [8GB x 1] 1600mhz or the [4GB x 2] 1333mhz based purely off that and not brands?

I'd go with the 2x GSkill set, it's 1333 but will run in dual channel so the DRAM will run as a 128 bit device (faster) than a single stick will, where it operates at 64bit, also it's GSkill which has been my favorite brand for over 5 years, and you're guaranteed (supposedly) to get GSkill rather than an up in the air Corsair or other brand. Think even if Corsair was guaranteed, I'd prefer the dual channel option, I always try and go for best performance options

thanks dude. one last question idk if u can answer itd be awesome!

Is the GeForce GTX 770M 3GB much better than the GeForce GTX 765m 2gb? Is there a substantial increase in performance? The price increase would be near $150... would that money be better spent increasing the cpu from 2.4ghz to 2.7ghz?

If your predominant thoughts for the system are gaming then the upgrade I'd say is a good maybe, these are both newer laptop GPUs and for a laptop, the extra GB of GPU DRAM would be nice - but then again for a laptop I wouldn't think I'd go that way unless I planned to hook up a decent size external monitor...For general use and gaming I'd prob put the bucks into the CPU

2x4GB 1333 will be just fine if it fits in your budget. As for the processor, I would go with the lessor of the two as at least for me, the laptop upgrade cycle is shorter than the desktop as upgrades are limited. You have a desktop for heaving lifting too, so really you don't need to spend a whole lot on your lappie. I didn't see a mention of an SSD, but as its a secondary machine its not really needed. On the other hand, a hybrid disk may right up your alley.

If you have Optimus, having dual channel will reduce frame latency due to the way Optimus works. Is it going to be a huge difference, I don't think so... But if you are using Haswell class hardware, go for 2 x 1600 Mhz.
