Hi everyone! I'm planning on buying a G75 but i'm not sure if I should buy from GenTechPC or TigerDirect. I've already set my sights on the G75VW-TS72 on TigerDirect but I found a similar one(G75VW-RS72) on GenTechPC that I can customize and come out to be slightly cheaper than the TigerDirect one with the same specs. And I'm going into college at the end of this year so should I get the Asus ROG backpack for the laptop? Also, does the wifi card matter too much?
