increased cost
raw gaming performance dropped significantly from previous post, will still be a big step up from your current.
limited upgrades path without also upgrading your power supply again.
Cons:
Corsair builder series is not of the same cailber as Corsair's other PSU lines
Dual core < quad core
All in all still a good build. I dropped the graphics card as the onboard 4250 will easily run what is being used already. A 4200 onboard is roughly equal to a GeForce 7600GT and the 4250 is just an updated version of it.
