220RMB, upgrade the CPU to 4-core Q9300 Q9200 Q8200.The highest is Q9550, but the power is large and the quantity is small.
ask
How high can the dual core reach
answer
The 4-core Q8200 and Q9300 are currently supported by software.The dual core is not worth replacing. I also forgot that the old architecture CPU has a high frequency, which makes little sense.
