Recommend Lenovo IBM E420 2yc notebook with the same price and level, which is knowledgeable. Thank you.

2yc is within 4400, which has never been used in China. I don't know. There are not many brands of GT540, except Shenzhou Acer. Needless to say, domestic brands other than Lenovo and Shenzhou in Taiwan Province Province are really not hard enough. Asus A43 series is probably within your range. Everyone buys a lot of GT540 graphics cards. This machine uses ASUS's ICECOOL technology. I think the heat dissipation is good, as well as Toshiba's L700 series and GT525 graphics cards. This machine looks good and beautiful. In addition, Gateway NV47H 18C is now under Acer. The price of the old brand is similar to what you said, and the configuration does not have to be very high. TPE420 for heat dissipation is also good.
