Are my specs good enough to run demanding games on High or Ultra settings in 1600x900?

High yes. Ultra @ 1680x1050 maybe. Any higher I doubt it.

Go for this one instead http://www.newegg.com/Product/Product.as... . Same price off the shelf and $10 cheaper after the rebate, higher clocks = SLIGHTLY faster, better warranty. AR instead of KR = lifetime warranty instead of 3 years.

GO for this motherboard instead http://www.newegg.com/Product/Product.as... . Still have the single @ 16 or dual @ 8 for when you go SLI. Only has 2 SATA 6GB/s connectors but also has 4 Sata 3.

You probably won't have more than 2 HDD or SSD drives needing that. It doesn't have HDMi but won't you be using the one on the GFX card anyway? Save yourself $50 and go for that one.

I have ran 2 cards in Xfire and now I only have 1 570 classified in there. I have overclocked the gfx card and my 2500K. I have 8GB in there as well.

It also handles just as much RAM and RAM speeds as the one you have posted. It is VERY stable with this RAM http://www.newegg.com/Product/Product.as... which is 1333MHz just like yours and 9 9 9 24 just like yours. Go ahead with Mushkin but I am just saying what mine has in it that has been stable.

It's fine that you are saving money but do you want to spend $59 now and then another $120 later or just $120( ONLY $79 atfer MIR ). Remember you saved $50 that can be reinvested in a better power supply. This http://www.newegg.com/Product/Product.aspx?Item=N82E16817194093 is a cheaper power supply but please just hear me out.

It is rated at 65 amps, it has all of these connectors 1 x Main connector (24 Pin) 1 x 4+4 Pin CPU 1 x 8 Pin CPU 6 x PCI-E 10 x SATA 4 x Peripheral 1 x Floppy 80 plus bronze certified and it's modular. I mean most lower end PSU aren't 80 plus certified much less 80 plus bronze so it will power 2 560ti and the rest of your hardware with ease. I was seriously considering the Corsair 850W PSU but now that I saw this in an earlier question I have changed my mind.

You also get a $40 rebate card. Which sweetens the deal even more. My specs Operating System MS Windows 7 64-bit SP1 CPU Intel Core i5 2500K @ 3.30GHz 32 °C Sandy Bridge 32nm Technology RAM 8.00 GB Dual-Channel DDR3 @ 665MHz (9-9-9-25).

I'm sure that it will run BF3 on high specs with no problem, in ultra will work fine but if you wanted to be sure you could always overclock it to be faster.

Maybe at high, I would definitely say NOT ultra, even though its a lower resolution compared to 1920x1080 games like metro 2033 are extremely demanding.

If you have a spare few dollars you get a mobo that has multiple PCI-e slots and you install a Revo drive into one of the PCI-e slots, an SSD drive that avoids the bottleneck of SATA drives with a 540MBp/s data transfer, you also ne to be able to boot over PCI-e , they are made by OCZ and cost $230 for a 50GB and go up to 500GB.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
