I cant sit around without games for 4 or 5 months bro...and do u really think that ill b wasting my money on the i3???
Ask your family or friends for a loan ($100) to cover the difference between a Core i3 and Core i5, and you'll payback within the next 5 or 6 months.
If you are really close, then they might just give you an interest free loan (meaning they just want $100 back). If they hesitate, then tell them you'll pay back with interest; like $105. Considering that most banks gives less than 1% interest on saving accounts per year and you are will to give back $105 in 6 months, that's 5% interest for just 6 months (effectively 10% per year).
