Compiled from www.rsm.co.il ( Israeli store ) - I don't know the prices in the states, but If it's cheap as much as it is here then this is probably the best you could muster with your budget. I would also like to add that you shouldn't buy RAM sticks with 1333mhz, because then you'll have less speed when the next generation comes, this is why I put 1600mhz.
Also, I choose I5 because of the budget, but if you can avoid i5 and get i7 - do it - Next generation games will run much much better and have much more support to i7.
