I am going to be getting a alienware X51 but I just need to help on picking the processor. I play quite a lot of games including project reality which is a mod for battlefield 2 I also play planetside payday. So I really need a good around gaming processor and the two that I can't choose between are
The i5 3450 (6M cache, up to 3.5GHz)
The i7 3770 (3.40GHz, 8MB L3 cache, 4C)
Yeah as I said it needs to be ready for some quite demanding games.
