^ The component selection is pretty good...but do you think you would need a 6-core?
You should know that in terms of gaming performance, it doenst offer any significant increase in gaming performance but does well in productivity and encoding though...but doest it warrant the $130 over the Phenom II X4 955/ 965 ??
But its you call though... http://www.tomshardware.com/reviews/amd-phenom-ii-x6-10...
^+1. A Phenom II X4 955/965 would save you cash and performs very closely to the 1090T, and IIRC, beating it in a few games. Also, I suggest that you get the Corsair TX750W - a very reliable power supply, $99.99 after rebate with free shipping, and has enough connectors for two HD 4850s, and enough power for two HD 5870s in the future.
Case: CM 690 II Advance
MB: Asus M4A89GTD Pro
CPU: Phenom II X4 955 BE
Video: 2 x 4870 512 MB DDR5
PSU: Corsair TX-850 (the TX-750 is ok for 2x4850 but a bit limited for 2x4870 or 2x4890)
As others said before me: don't buy a 6-core Phenom, it brings nothing to games.
I would suggest you to buy an aftermarket CPU cooler like CM Hyper 212 Plus or Scythe Mugen 2 Rev. B which bring amazing value and cooling for the cash and Overclock the CPU to at least 3.6 GHz.
This way you'll beat the X4 965 BE with less money... personally I keep my 955 @ 3.8 GHz.
The motherboard is amazing, the PSU is amazing... really solid choice both of them.
As for the CPU... well it's the best gaming CPU from AMD until next year so no other option atm.
Good luck with your rig, I'm sure you'll enjoy it once it's ready!
Have been mulling over the CPU choice for a while, and I wish the 960T would drop so I could compare it. Was initially leaning towards a 955/965, but I can get $50 off the 1090T from MicroCenter, so the price differential isn't as significant. Was hoping it might last a bit longer if more games come out with multi-core support in a few years.
^ Well +1 for the 955 over 965...with an after market cooler, you can overclock it to higher speeds without any issues...
But as for the PSU, A Corsair 750TX provides more than adequate power even for 2x HD 4890s...
Here @ TOMs, they tested a CyberPower PC which was running an overclocked 955 with 2x HD 4870s on a Corsair 650TX...
And recently they built and reviews a PC which was running 2x HD 4870s with the Antec EA 650...
So the only thing still not decided here is the CPU selection, that is upto you...You know the facts, its your decision to make...
@gkay09 I would normally agree on the PSU with you but what you (and probably those reviews) didn't bring into the equation is the overclocked CPU.
At stock frequence it feeds on 125W, overclocked it can pass 200W easily.
The 4870 eats 250W at full load so 2 of them are 500W
Add some hard disks, USB devices etc and you'll notice that 750W is not that much. It works, but it's limited.
That's why I went for 850.
For his config, 750W is more than enough and a solid choice
^ Well as for the PSU, I would say the 650W is not much when taken into consideration an overclocked CPU and 2x HD 4870s...
I highly doubt the CPU would hit 200W...Even with an voltage increase to say 1.45V, you can easily overclock the X4 955 to higher levels - even 3.8GHz easy with an aftermarket cooler...And that would translate to around 170-175W TDP...
And as for the graphics card, I think you are talking about the GTX 480's TDP levels
I have not seen or heard that a HD 4870s would consume about 250W, even at full load...
And am just clearing out things here
