ok i have a 2500k cpu and a r6970 gpu. my question is it nessesary to overclock my cpu. i will be wanting to play bf3, skyrim and rage fully maxed at 1920x1080 and get between 50 and 60 fps. i am currently getting apx. 40-40 fps in witcher 2. is my cpu holding my video card back or was the game just not optimized the best. anyway im just wondering should i overclock or would it work just fine for those games if i leave it alone. thank you.
