Intel sandy bridge 2600k cpu

// Mobo Asus P8Z68P, Corsair HX1050psu, Corsair Vengeance 16GB, Corsair H80 cooling, WD 640GB HD, Crucial SSD 128GB x2, six fans, !-EvgaGTX560Ti graphics card.
I would like to get a pair of better performing Graphics cards, cost is not a great issue. My cooling is adequate to run hotter cards. I want to play some of the newer games.

 


Thank you, I take it I can just drop these graphics cards into my system as it stands, correct?
Best Regards
 


I forgot one major item, I have a Samsung UN32EH5000FXZA monitor, also checking the cost of the 670's I thought it best to go for a EVGA SuperClocked+ 03G-P4-3663-KR GeForce GTX 660 Ti 3GB 192-bit GDDR5 at good savings. What is your opinion. Thank you
