Why don't you opt for a X58 setup! You've a good enough budget for that.. And btw, are you sure you need a blu-ray burner.?
I might have the budget in the US but for imports is like one fifth more... so it exceeds I think... by the setup I used the whole computer costs $1697... I think it was like $2300 if I use X58... or maybe you have a cheaper setup?
And no I dont need one but since I am going to change my burner why not upgrade it too instead of buying another exactly the same?
