The main issue is that both the future Intel standard and high performance processors will have different processor sockets!! The i7 has socket 1366 and the i5 has the socket 1160!! If I were getting the i7 I would wait for prices of the motherboards and RAM to drop. The £350 cost for the cheapest socket 1366 motherboard and 6gb RAM is too high in todays market!!
Wow!! My 1000th post already!!
