尋求更換CPU的建議

如果不換底板的話, 因為可支援的 CPU 已停產多時, 只可以在2手市場上尋找, 最好換 Core 2 Quad 6000/8000/9000 系列的 4核心, 例如 Q6600 或 Q8400, 大約 $600-800 左右, 購買前可先到底板牌子的官網, 查核有關型號可支援 CPU.
例如 :
Intel® Core™2 Quad Processor Q9650
Intel® Core™2 Quad Processor Q9550S
Intel® Core™2 Quad Processor Q9550
Intel® Core™2 Quad Processor Q9505S
Intel® Core™2 Quad Processor Q9505
Intel® Core™2 Quad Processor Q9450
Intel® Core™2 Quad Processor Q9400S
Intel® Core™2 Quad Processor Q9400
Intel® Core™2 Quad Processor Q9300
Intel® Core™2 Quad Processor Q8400S
Intel® Core™2 Quad Processor Q8400
Intel® Core™2 Quad Processor Q8300
Intel® Core™2 Quad Processor Q8200
Intel® Core™2 Quad Processor Q8200
Intel® Core™2 Quad Processor Q6700
Intel® Core™2 Quad Processor Q6600
Intel® Core™2 Quad Processor Q9100 Intel® Core™2 Quad Processor Q9000

Flash game doesn't need Quad Core, but high core frequency at least 3Ghz is necessary indeed !!!

So Core2Duo E8400 or E8500 would be your target, you can get it around $700 to $800 from 2nd hand market...

The Q6xxx series core frequency is too low

The Q8400 is only 2.66G

The Q9650 3.0G cost around $1700 in the market exceeds your budget la !
