970GTX SLI Query

[Cromat]

Hey guys,

 

Specifications:

 

CPU: Intel I5 2500K @ 4.5GHZ 1.3V
GFX CARD: MSI 970GTX Gaming 4G
RAM: G Skill Ripjaws X 1600mhz 2GBx4 1.5V
MOBO: MSI P67A GD80 (B3)
PSU: Cougar CM 1000W @ 80A
PRIMARY DISPLAY: Benq XL2411Z 1920x1080 144Hz 1ms
SECONDARY DISPLAY: Sony Bravia CX52 32" 1920X1080 60Hz 5ms
OS: Windows 10 Pro X64
 

As per above specifications, I am looking to get another 970gtx for SLI to make the most of my Benq 144hz screen since one 970gtx doesn't seem to cut it in some of the titles i play. My questions are as follows:

 

1. Will my current PSU be sufficient to run two 970gtx in SLI? Ive had this PSU since 2011 and its performed flawlessly since then. I used to run two 560GTX TI's on it and they were both overclocked with no problems.

 

2. Should I be concerned of any potential bottle necking on a 2500K? I think this is unlikely due to it still being a Tier 1 CPU and mine is running at 4.5ghz. But would just like a secondary opinion on this.

 

3. I was thinking of just getting a 980gtx TI but at my current stand point and location (South Africa) it is not financially possible. Trying to sell one 970gtx to get a 980gtx ti just wouldn't work in my current financial standing.

 

Any help regarding this would be appreciated.

1 - likely fine
2 - likely a bottleneck
3 - likely better

LIKELY!

Bottleneck, Likely. And you could power Vegas with that PSU.

Yes

No

Yes

You won't experience much bottlenecking, depending on the title. But yes, your power supply can power 2 GTX 970 cards with no issues.

Hey guys,  Thanks alot for all the replies! I can understand bottle necking concerns at this point , hence the age of my CPU. However getting a extra 970GTX is going to cost me a whole lot less that buying at brand new CPU, Mobo and RAM. I mean I can try and fine someone sell my 970gtx to but its going to be very difficult in the country i stay in.

Bottlenecks don't care why they happen, they limit performance the same if it's the CPU, GPU, or RAM. Been there.

Overclocking the CPU would help to alleviate some of the bottlenecking.  You'll just have to test to see which titles give you problems, and try to keep as much pressure on the GPUs as possible.

PSU is fine.

Bottlenecking 50/50

Thanks for the replies guys, but I have decided to get a the 970gtx now and get the CPU/RAM/MOBO later.
