Im on the lookout for new ram and want to know if its worth paying the £40 ish difference between these 2 sets of corsair ram: TWINX1024-3200XLPRO and TWINX1024-3200XLPT. Seeing as they both claim to be happy running 2-2-2-5 latencies and 250MHz with 2.5-3-3-7 is the extra cash just to pay for the pretty flashy lights?
