Upgrade from GTX 470 to GTX 660ti worth it for idle power difference and PCIe 2.0

post #1 of 3
Thread Starter 
I'm currently running a GTX 470 which most of you know is not too power friendly.
I don't use SLI or any multi-monitor gaming 120hz display. I'm perfectly fine with gaming with a single 1080p 60hz monitor. Games like Witcher 2 and Batman are a pain but I don't play them too often. I'm more into Mass Effect and such. (I'll continue playing them if I upgrade).
I do use multi monitors, however the later is plugged into the iGPU so it's not drawing the GPU during idle.

This computer is powered on literally 24/7. It is a server comp and gaming comp. At times it might be off only 5 hours a week. So idle power consumption is a concern.



Even if I don't play such graphically demanding games as often as others (Do play them anyway), is it still worth getting the 660ti even for its power saving features? That is, if we add the wattage savings over a 1-year period, could I reach a point where I effectively bought a 660ti using wasted idle power?


Currently deciding over Galaxy or MSI pe.


My board is PCIe 2. Not sure about much of a performance hit this would cause. But multiple reviews claim it's only about a 1-2 frame hit. However, seeing as PCIe 3 is 2x the speed of 2.0, the 470 being 320bit 2.0 while the 660 is 192 3.0; the numbers are close so the performance between 320 2.0 and 192 3.0 should be practically null.

definitely its worth getting a GTX 660 Ti . you will save power while at idle and load. how much of a reduction in your power bill might be tough to say. But you would definitely have paid off a portion of your GTX 660 Ti cost through reduced power costs especially because you rarely shut it down.

If power consumption is a concern get a 660ti for sure. There's a good write-up about power efficient in the Guru3D review of the MSI card.. I really don't think you'll notice any difference between PCI 2 and 3.
