CPU Bottleneck for SLI GTX980 (980X)?

[Antx777]

Hi there.

Been looking to upgrade my old GTX 480 SLI's to a GTX980 SLI set up (or 970sli) However, I was wondering if my system as a whole can "hack it" with these latest cards? most of spec in sig. my i7 980X cpu is O/Clocked to 4.2 (1.30 v)or 4.4 Ghz if I want (1.36 V).

Will the cpu (or anything else in my system) hold it back?, I gather I wont get same frames per second as say a modern 6 core cpu (or perhaps a quad one) but answers on this would be appreciated.

Res is 2560x1440 (dell monitor) I'm assuming my 1200 psu will be sufficient?

Should be fine, plenty of life in those chips yet

as above cpu should be fine, HDD speed is the major factor I see you have the same storage I have (120gb + 1TB HDD) and I'll hold my hands up my drives are virtually full and I'm constantly deleting games or moving them on/off my SSD

1.36 V? that little beast must get toasty

... and the 1200 psu is still overkill - the power draw of the 980s is so low its ridiculous

Not really as overkill as you think.

His CPU is probably pulling something like 350-400W, and the 980 still pull around 190W each under max load, so they still comes to around 750-800W+ total power consumption

No such thing as overkill

 

[Yaayuh!]

Yep, will be fine. As said, those chips have life in them when overclocked past 4GHz

well @4.4 GHz it is 1.38.2 in bios. with readings of 1.368 in CPU Z. not sure which is the most accurate though.
