Hello,
I want to upgrade my gpu and I have couple question.
I decided to buy the GTX560 Ti and now I have dilemma which model to buy.
I have 2 options (I live in ISRAEL so there is no large selection like in the US).
GigaByte GV-N560OC-1GI Or GV-N560SO-1GI-950.

This is my spec:
Processor: Intel Core i7 920 8M Cache, 2.66 GHz, 4.80 GT / s
Motherboard: Intel Desktop Board DX58SO
Memory: G. SKILL 3GB Kit DDR3 PC3-10666 CL9
Graphics Card: Sapphire ATI Radeon HD5450 512MB DDR2
Power Supply: Seasonic SS-500ET (two rail 12v 1. 17A 2. 17A)
Storage: Intel X25-M G2 80GB + Samsung 500GB Spinpoint F3
Case: HEC Compucase 6A19B
Screen: Samsung T220P - Resolution 1920X1200

The only cause of my dilemma is the subject of power consumption.
Is my PSU can handle with one of the GTX560 Ti model + core i7 920 stock?
I prefer the GV-N560SO-1GI-950 but I'm afraid that my PSU will collapse under the effort.
According to this presentation (http://www.businessdirect.bt.com/content/uni2/documenta...) the GTX 560 Ti OC is 12% power consumption lower than stock GTX 560 Ti. Does that make sense?

Thank and good day

I don't see how an OC card will have lower power use.
Here is a full load example of that card http://guru3d.com/article/geforce-gtx-560-ti-sli-review..., it looks to run the system and card to 450watt, for a gaming system.

You'd want a 600-700 watt quality PSU to handle that to be safe from frying something.

in the review the writer say that "On your average system the card requires you to have a 500 Watt power supply unit." and the system that analyzed is core i7 965 OC and I have i7 920 stock?

You can always try with your PSU first, chances are good that even if it does not work it won't damage anything.
