Hey guy,

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.
 
Solution
1. Yes a 1000w PSU is capable of running 2 x GTX970 in SLI.

2. There might be a slight bottleneck as the best CPU match for a GTX970 is a i7-4770K.

3. The same PSU would run a GTX980, i7-4770K is also a best CPU match for a GTX980.
