Comparing the RX 6600 + GTX 560 Ti with a PS3 offers a clear picture of performance differences across gaming platforms.

Consider what matters most to you and make your decision accordingly.
C2Q and 560ti are great options unless you need something from the PS3. The PC offers stronger performance (better graphics even with that setup), greater versatility, and will remain compatible for a longer time.
What RAM do you have? Which motherboard? What cooling solution are you using? If all these fit overclocking requirements, consider going for the PC instead of the PS3 as suggested by Weak1ings—you might achieve better results for around $300. The parts I mentioned earlier could help, but his statements seem questionable. If your components support overclocking, performance will improve. Also, what type of monitor are you using?
For quick reference: here is an actual relevant comparison: http://www.anandtech.com/bench/product/1337?vs=1130 I'll make that $300 build then.
