I got the impression those were the items he was thinking about buying, not that he already owned them. If he does own them already then yeah no need to buy new ones.Why would he buy a new mobo and new 2.5ghz processor when he already has a 2.9ghz processor capable of 3.1ghz? Doesnt make sense.
And why a new power supply? His power supply is perfectly capable of running at least a 4850.
