Quick questions about my rig

post #1 of 5
Thread Starter 
I recently did my first pc build and while I am happy with the results so far I have some questions about my future plans of adding SLI to it.
Here is my current specs:
Mobo: Asus Sabertooth 990FX
CPU: FX-4100
GPU: EVGA GTX 560TI SC
RAM: G SKill8GB DDR3 1600
PSU: OCZ ZS 750W
SSD: OCZ 30GB SSD
HDD: 1TB Deskstar
OS: Windows 7 Pro

Now for my questions.
Is my CPU a bottleneck?
If I add another 560TI for SLI would it become a bottleneck?
Should I wait for Piledriver or get a 960T?

I thank you all for you help in this matter.

I wouldn't think that CPU would bottleneck it. You will see an leap in FPS.

Either way.. Go SLI and then when Piledriver is released buy it anyway if the money is right.

Cool, I just have been getting less fps than I wanted with my new 1080P resolution. So if neither CPU is a bottleneck for my SLI I'm just gonna go SLI it and wait and see how piledriver is.

Someone might correct me but at almost 4 Ghz Turbo I don't see how it would be even enough to matter.

With a little overclocking I would think it would be utterly non-existent.

The only thing I see being a bottleneck with SLI is the PSU. One review said you needed 700+ for it stock and 800+ with everything overclocked depending on how much was running (ie sound card).

I'm OCed to about 4.15 Ghz. I have had it stable at 5.0 Ghz but I felt I was using too much power. It idled at about 45C then but now it's at 28C. As for PSU I hope that it's enough. I'm not running any other cards and the only thing that pulls my watts except for the above listed is my eight fans and cpu waterblock. Six case and two for my cpu radiator. I run all the case fans on low so they are quiet and draw less power.

EDIT: I found some info.
For a system using two GeForce GTX 560 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater power supply that has a combined +12 Volt continuous current rating of 44 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.
My PSU has +3.3V@22A, +5V@22A, +12V@54A, with 2 x 6-Pin and 2 x 6+2-Pin.
This means it should be able to handle it even with my OCed CPU. I will admit I am pushing it lol. But I can always back off the overclock on the cpu.
