Curious about Video Cards

With this setup:


- Windows 7 Professional (64-bit)
- Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz 9.04GHz
- 8.00 GB RAM
- Video Card: EVGA 012-P3-1470-AR GeForce GTX 470 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
- Mother Board: EVGA P55 FTW SLI 132-LF-E657-KR LGA1156 Intel P55 ATX Intel
- 650 Watt power supply (came with the Antec Case)

Can I swap the video card to the GeForce 660 Ti without have to replace anything and without the old parts limiting the new card? I'm using it with 90% intention to simply game, and am trying to get better visuals from games such as Dead Space 3 and Bioshock Infinite. Thanks!

 

Yes. I've done it before. From the 280 gtx, 5870, 580 GTX, 680 GTX, etc

I'd recommend re-installing the drivers, just to be safe.
