the answer is easy.
i'm currently doing a bulk on the Tuhbo buttan

attached it to your usb port and press it when you need 5ghz.

selling it at rm 55. ( your spec would not change but your internal processor clock will be supercharged with millions of neutrons energising it so it performs on par with 5ghz clocked machines)
Item comes with
1x Tuhbo Buttan
1x Usb interconnected cables
2x Spare Tuhbo Buttan Knob (Handy when u start smashing your tuhbo buttan ala NOS)
1x Processor Replicator ( By using this, it would replicate your processor and make it run in a dual processor enviroment. Stick it on top of processor to form a sandwiched processor and see them work flawlessly together)
