I'm looking at Motherboards for my PC build, I had decided to buy the ASRock X79 Extreme 4 for around $240 but I was looking on the online store of the shop I buy them from and I saw they had a demo Motherboard they were selling for $80. It is the ASRock X58 Extreme Motherboard. http://www.asrock.com/mb/Intel/X58%20Extreme/ I'm thinking of buying this because it's alot cheaper and it's regular retail price is $300. So do you think this motherboard is good and worth buying instead of the ASRock X79 Extreme 4 motherboard? I know some of you really like computers so I'm asking here, Also which would you buy the ASRock X79 or the ASRock X58 Extreme Motherboard.
