wow for the price of that laptop i could build a decent desktop... i bet you wish you had gone that rout now 2...
but thats by the by...
mouse. logitech g700 is hard to beat... at the price and they perform reasonably well, better than most other wireless mice in fact.
as for keyboards microsoft do some cheap but well built wireless 1s. it would be a waste of cash if you went for a gaming wireless 1 as ther no better than a business class 1... your talking a 30 percent permium for the word gaming. thats all.
