Pros: I purchased Corsair 1600mhz 4gb(2x2gb) to replace my Patriot 1333mhz 2gb(2x1gb). The cas timings were slightly higher on the Corsairs. I was originally concerned but the higher frequency(1600mhz) on the Cosair gave me headroom to further overclock my CPU and Motherboard. Ran great with fantastic stability.

Cons: none so far.

Overall Review: Vista Service Pack 1 Q9450 @ 3.30 mhz 4GB Corsair DDR3@ 1408mhz in duel channel mode.

Pros: This has got to be the best piece of junk I've ever purchased. The cheap material made the case really light and easy to carry around. The case looks really cool.

Cons: This piece of junk had a stripped screw hole on the back and would not screw on right. It appeared that i may have recieved a returned item. Furthermore, the bracket holding the PCI and PCI Express cards in place to the back of the case would not really hold my MSI 8600GTS OC in the place without force(and risk damaging both the mobo and the video card).

Overall Review: It did come with a decent power supply but you sacrifice quality not to mention the absense of rear fans. Do you really save money with this product? In the end, you get what you pay for.

Pros: was able to unlock the 4th core and even overclock it. passed prime 95 and didn't require any voltage tweekings.

Cons: i kind of wish i was able to get above 3.2 ghz, but at the same time, hey, i got the 4th core up, running, and stable.

Overall Review: Phenom II x3 710 2.6 ghz running at x4 3.0 ghz bus speed set at 231. 4 gb DDR2 OCZ Gold 800 mhz @ 924mhz

Pros: It runs increadibly fast compaired to my old single core AMD Athlon 3400+. This was an easy install and had no problems.

Cons: I don't think there are too many other chips that can be upgraded above this for a 939 socket.

Overall Review: I strongly suggest purchasing an AM2 socket mobo and chip. The life of 939 chips are pretty much over and I believe the mobo's for it don't support DDR2. AM2 sockets on the contrary seem like they are here to stay for a while.
