If you are looking for laptop for gaming you should look for machine with best GPU. On newegg in this price range the best solution will be:
ASUS ROG G751JY-WH71 $1600 most important features:
- i7 4th generation CPU
- GeForce GTX 980M
- SSD 128 GB
- 16 GB DDR3 RAM
In your price range it will be best solution because of GTX 980M GPU. It is the most important part for gaming in laptops. The rest will also meet your requirements. It has no USB 2.0 port but USB 3.0 is backward compatible so you can use one of USB 3.0 slots for USB 2.0 devices.
If you are from Croatia like your profile says, it will be a little harder. I checked that €1500 is around 11500 Kn so I looked for laptop which meets your requirements in Croatian shops (I'm not familiar with Croatian market it would be easier if you provide some "good croatian shops url's") and I found:
Acer ASPIRE G9-591-73PJ Predator 15 - 11000 Kn on ekupi.hr:
- 6th generation i7 CPU (6700HQ)
- 8 GB RAM DDR4 (it is enough for gaming)
- GeForce GTX970M (worse than ASUS but should be enough for most of new games)
- no SSD drive
- no operating system
It is much worse than ASUS but it's best solution which I could find on Croatian websites. I would look for something with GTX 980M if it's possible in this price range in Croatia. If you provide me with url's of "good" Croatian shops with laptops I will look what you can find there.
