Revised again (This time I'm set! For real!). Just check if everything is compatible again please. I changed the PSU to a Corsair 650W b/c the 750W is too much for this rig (I think). Also, I changed the mobo b/c I thought the ATX form would give more space for the memory and the vid card. I upgraded to a Phenom II X4 955 and changed the memory to the G skill 7-7-7-21 kit because the ECO series doesn't run at 7-7-7 timings on the AM3 platform. ;_; Finally, I switched to a Cooler Master HAF 922 b/c I didn't wanna deal with crappy standoffs that came with the Antec 600.
Edit #2: Switched to the Gskill ECO 1333 Cas 8 memory b/c it was the only ECO that was below $100 and was listed on the mobo's memory QVL.
Edit #2: Switched to the Gskill ECO 1600 Cas 8 memory. After some research, it seems that as long as it's at cas 8, the memory should work fine, even at 1600.
Again, thank everyone. I will buy these parts today if they are compatible and doesn't require any drastic changes.
Thank you for your G.Skill purchase and review. Unfortunately on most AMD platforms you will need to use CL8 instead of CL7 at DDR3-1600. It may be a BIOS limitation, so you will want to check with the motherboard manufacturer to make sure you have the latest BIOS that may resolve the issue. You are correct in that lower voltage equals lower heat emission, but many motherboards can not set memory voltage that low, so you will want to make sure they can otherwise you will not be able to benefit from the low voltage. If you have any further questions, please feel free to let us know.
I already ordered everything guys. I decided to get the Gigabyte 460 because it has a full 3 year warranty. Also, the RAM shouldn't have too much of a difference in gaming. Finally, the AsRock mobo only has a one year warranty.
If I was experienced like you guys are, I'd get some of the parts you guys suggested but this will be my first build, so I'd rather get parts with long warranties. I'd rather not take any risks.
But yea, thank you very much sp12 and Timop. I will try to post pics/benchmarks after I build this thing. It should be fun.
