I think it is better off to buy a new one since my current laptop is more than 3 years old. But it takes a long time for me find out which laptop to buy. I haven't pay any attention to the new development of laptop technology and don't even know what are the current processors in the market.
After much readings, I settled with Acer Aspire Timelinex 5820TG. I need to buy a laptop that can allow me to work on large graphic and image files. I use the following criterion to choose the laptop:
- Must be dual-core processors for better multi-tasking work
- Large system memory at least 4GB with 64-bit OS
- Quadro Nvidia or Radeon graphics
- Big screen
- Better function and Price ration
- Screen should be sharp under day light
Acer 5820TG uses i5 processor. The i7 processor is the more advanced one currently. I was thinking of buying Lenovo Thinkpad w510 that uses i7. But comparing the cost and function, I choose Acer. The Lenovo is double the cost of Acer. However, I read from some articles and they claim that i7 may not necessary much better than i5 considering the price you have to pay. Looking back at all the laptops that I have used, they all broke down after 2 to 3 years. I think it is better to choose one that is cheaper and with good functions.
