hi there,i'v just brought a laptop from trademe its a acer aspire 5740 i3 330m 2.13 GHz or so it says on the stickers on the case of the laptop(also on the listing on trademe as i was looking for i3) but funny thing is when i check the performance information and tools on the laptop it says intel(R) core(TM) i5 cpu m430@2.27GHz,how can this be?im happy with it as its running great but cant under stand why anyone would upgrade this to i5 when you could just buy one!thanks
