the dual slot 4870 will beat both of those single graphics core based cards in most games. however, it requires substantially more power. your psu takes care of that problem. i like the ram selection as that was the one i selected for my i5 build. low timings and the manufacturer has a good reputation in my book for overclocking. Speaking of overclocking, why not save a few bucks and go with the i750 with a better cooler. This one in particular if you don't mind a blue led. (http://www.newegg.com/Product/Product.aspx?Item=N82E16835118046&cm_re=cpu_cooler-_-35-118-046-_-Product)

the 4870x2 is no longer being manufactured and will concurrently be more expensive and difficult to find. my question to you is- What is your monitor's resolution? If 1920 by 1080 or 1200, i like these in crossfire

They are faster than the gtx260 and can be found at a lower price as that particular nvidia card is being phased out and the manufacturing costs have gone up. For a single card solution:

this is comprable to two gtx260s in sli while using substantially less power. Not sure what your budget was so i stayed below $300. In this age, spending more than that on graphics cards is absurd as most of the modern cards are more than enough for even extreme gamers.
Not an ati fan or nvidia hater, i just buy what is the best at the right price
You seem have alot of money to throw around with these components you have picked out. Both motherboards you picked are pretty gangster.
Check this out (http://www.newegg.com/Product/Product.aspx?Item=N82E16813130238) I'm under the impression that you will be overclocking and this board is terrific, backed by professional reviews so i have some credibility. that maximus by asus, a great brand, is also fantastic at pushing your i5 and has a great audio card. That price bump is for a reason. Your power supply selection is fantastic. I own the same one in a 520watt flavor and i love it. Corsair is terrific with warranty and parts replacement. Not really a positive mark, but my power supply bricked due to a fried transformer and they had a new one out to me within the week.
I chose the Radeon 4890 over the new replacement 5770 because it has double the core memory at 256-bits. This is what matters most in games, with exception to physical memory. Yes the 5770 does run a tad cooler and is direct x11 ready but that is not to be implemented in an OS or games for that matter anytime in the near future. If you can find the 5770 with 256-bit ram and under $200, by all means go for it.

The WD Black 2TB model is a great performer with its 500 GB platters but it is currently the only one on the Black line to have them. The rest have 250 / 320 GB platters which are a previous generation and slower drive. If not springing for the 2 TB, get a 500 GB platter drive from Samsung (Spinpoint F3) or Seagate (7200.12).

With the 5770 or 260, no need for more than a 650 watt power supply. Move up to a Corsair HX or, even better, for the added quietness an Antec SG-650.

The 260 and the 5770 are comparable cards, the 260 Core 216 consumes more power @ 91 watts (older 260 consumes 28 more) than the 5770 @ 57 watts but is about 8 % faster. That extra wattage will cost you about $6.36 a year at 36 hours of max draw per week. The 4870x2 is in another league....about 40% faster than the 2 The 60. The 4870x2 (800/3600) consumes 244 watts or about $45 a year at same usage. I hit 661 watts in the PSU calculator with your system ....allowing for future adds (OC'd to 4 Ghz, 2 HD's, 2 Opticals, 4 fans, 5 USB, 1 firewire, 1 sound card) so an 850 watter would be better choice for the 4870X2.

The boards you have selected are generally chosen w/ serious OC'ing in mind. Can drop down a notch if that's not in the plan.

but between the maximus 3 formula and the sabertooth 55i which is better?
