A:AnswerDon't know, sorry. Unless you are buying in bulk directly with the headquarter warehouse, I highly doubt you would get an extra discount. Best Buy has the best prices for all products in the industry and they price match any advertised offer.
A:AnswerThat's going to be the cap on the board, but you can. The chipset is compatible. You'd be better off with an i5 build though, and depending on what you're doing, something with a proper GPU.
A:Answerprobably not or it will be really slow. I tried nba 2k14 and it played but too slow. GTA 4 on low, possibly? games like max payne 2 work fine, Vice City should play ok.
