(I know this is a bit off-topic) I was also wondering what frame rates would I get when playing graphically intensive games on MAX settings like Crysis 2, Battlefield 3 etc. at 1366x768 resolution using the above card.
Although I am not a fan of Coolermaster in general, the parts you have selected will have no trouble with games at that resolution. In fact, if you have no plans to increase that resolution, you could save money by getting a less expensive GPU, like a HD6770. At lower resolutions, a larger proportion of the "effort" required by your PC will be done by the CPU. You may want to consider an i5-2300.
