No way! A 2500K won't bottleneck a GTX 560 Ti. On the fixed benchmark, Resident Evil 5 runs faster with a i7-2600, but try to look at the numbers from the variable benchmark.
I also looked at task manager with the Resident Evil 5 fixed benchmark running, the my i5-2500k was running at half of it's power, and the GPU usage reported by MSI after burner was lower than 50%.
My display is 1440 x 900, the numbers may vary at higher resolutions.
