I am currently using a system with very similar specifications, i am extremely pleased with my ASUS motherboard and i5 2500k. Newegg is neglecting to let me view your chosen items but your build looks great from what i can see!
It's not Newegg; it's the OP's pasted links, complete with Tom's inserted ellipses
Get a mobo that can handle Xfire. The LE's second PCIe slot is limited to x4. Try the ASRock Z68 Extreme3.
At $35, the Hyper 212 EVO's definitely a better heatsink.
I think you'd be much happier with a 120gb SSD, as 64 will fill up awfully quickly and require careful management. I know it'll put you $50 or so over budget, but I think you won't regret it. Maybe get a 500gb HDD to save money.
