You may or may not have heard of W450, but it is the cheapest quad core smartphone on the market right now. Its CPU is the newest MTK6582 with 1.3 GHz frequency, and has a nice 4.5 inch screen. I have ran Antutu on the phone, and the score is very very impressive.

I think the phone offers a lot for this price. I am testing the phone right now and a more detailed review will follow up soon. And at GeekBuying there is a special Thanksgiving Smartphone Sale going on right now. You guys can check it out
Items on sale includes Ulefone P6, UMI X2, THL W200, Cubot ONE, DG100, Haier W718, etc.
