Hi folks,

I'm looking into buying my first ROG laptop, and there are lots of variations to choose from. Ive narrowed it down to either the "old" G751JY with 16GB RAM and the 980M(win8), against the new G752VT with 8GB RAM and 970M(win10). They are fairly the same price range.

So, what do you people think, is it worth getting a newer model with newer CPU, while loosing RAM and a downsize in GFXcard, against the older bigger brother?

buy the older version, it has more battery capacity (3,5 hours vs 1,75 hours) and better GPU. The CPU difference gap is very small and games usually use less than 30% of your total CPU capacity.

I'd buy the G751 just because I don't see a point in buying anything less than a 980M at the price that they're available now...and also because the new gen will come out soon and you need the best you can get for the money you have to compete - new games will come out to work with the newer hardware and you shouldn't be left behind if you want a good gaming experience.

Otherwise, I'd wait for a GTX980M G752VY to come down in price and just get that.

There are a few main points to look at, and lets start right away with the main difference first:

-The 980m is much more powerful than the 970m. The 970m will pull 72FPS average in BioShock Infinite but the 980m will put 91FPS, and Crysis 3 gets 33 vs 43FPS respectively. The Video Memory on the 980m also has an extra gig of ram giving you a total of 4GB with the 970m has 3GB. These difference can really make the difference between high and ultra on todays newest games.

-The next is the CPU. The 752 has the Skylake chip. This is a less power hungry CPU so it will slightly extend your battery life. Its also about 20% faster than the chip in the 751. For gaming this means you will pull about 4-5 more FPS. Its not a huge difference.

-DDR3 vs DDR4. The 752 offers DDR4 made possible with that new skylake chip. This ram is much faster than DDR3. This can produce slightly lower loading times and will push the overall speed of the laptop by small percent.

-The 752 Offers a Thunderbolt 3 port. This is only good if you intent to use Thunderbolt 3 devices, or anything USB-C. Thunderbolt 3 is extremely fast, but the devices that use it are extremely expensive.

-They are now offering RGB back lit keyboard keys. This can look really cool for customizing your keyboard.

-3D Vapor Cooled CPU & GPU. This is new technology used in the latest Graphics cards, designed to help keep your chips as cool as possible. This can be beneficial for overclocking.

These are the main differences. The main thing to consider here that GPU. Yes the newer laptop has faster RAM and a faster CPU. However, since its using the 970m, it will still be slower than the 751 for games. Also, you can buy the G751JY for $1,499 right now that has the 980m, but the 752 with 970m costs about $250 more. Even if you decide to wait for the 752 with 980m in December it going for $2,500. That's a thousand more dollars for a minimal performance increase. Don't get me wrong, it looks amazing. But $1,000 is way to much for such a small performance increase.

According to german notebookcheck, the battery life on G752 JT is much worse than on older G751JY. Any positive effect on the battery life due to power efficiency of the newer CPU is negated by the smaller battery.

Its also about 20% faster than the chip in the 751
According to Passmark benchmark score, the 6700 HQ beats the 4710 HQ by a mere 2.77% on average.

Geez, I was going over of TDP on the CPUs and Early estimates of performance increase. That's pretty bad. It sounds more and more like your much better off getting a G751JY.

Dang the 980 makes that much of a difference huh? I guess it is a no brainer to go with the 751JY over the 752VT equivalent. Cyber Monday deals available until Wednesday have the 751JY for $1499 and the 752VT for $1528.

Thank you very much for the detailed posts. I will definitely go for the G751.

To bad I didn't get it on black friday, it had a nice discount, and couldn't find it anywhere on cyber monday. Also thx for the amazon link, but I don't live in the US, so guess I'll have to wait it out, until another offer shows up in the future.
