Blog "Chess Engines Diary" - needs a new laptop for chess engine tests

♔ We use for testing only 2 old laptops:
1. Acer - Intel Core i3-3217U ( 5 years old)
2. Lenovo - Intel Core i7-4710MQ is over 3 years old (He works 24 hours a day)

♕♞ A modern laptop that will be designed only for chess engine tests costs (with software) about $ 1000-1200 (4200-4500 PLN). We will no longer invest private money, and chess engine testing costs are big. That is why we are starting the collection for the purchase of a laptop for testing.

♕ Our blog "Chess Engines Diary" is visited by around 2,000-3.000 users daily. If only everyone paid 1 dollar - we will pay the required amount in one day!
