Re: First Gaming computer Build!!
I'd go for the Intel board over the BIOSTAR one, just because BIOSTAR have a reputation as cheap and cheerful, and Intel are market leaders. No other reasoning than that really.
Usually you'd use the SSD for the OS, provided massively improved loading speeds and general out-of-game performance, as well as any additional stuff installed on it.
Not sure about the PSU, but then again im not in the USA so i've never heard of it, i'd personally stick with Corsair or Coolermaster.
EVGA SLI Micro Z68 // Intel i5-2500k // 8GB Corsair Vengeance 1866MHz // Overclocked 2GB MSI R9 270X // Corsair Carbide SPEC-03 // Kingston Hyper-X 120GB // 2TB WD Green + 500GB WD Black
