Going from 580 SLI to 7970 CF?

post #1 of 2
Thread Starter 
Got a good deal on 2 7970 today (Sapphire Vapor X 3 GB version new). I will have about 30 days to return them. Just wondering what kind of upgrade this will be when compared to the 580 SLI set up I have now. Reason I bit on them without doing research was because of the price ($220 each). I always buy first and ask questions later.

I run a single 1080p 120hz monitor. Should I keep them? They should be here in a week.

very significant upgrade . 45 - 50% on avg with newer games like BF4 showing a doubling from GTX 580 SLI to HD 7970 Ghz CF

BF4 Multiplayer (siege of shanghai)
http://www.sweclockers.com/artikel/17810-prestandaanalys-battlefield-4/3#pagehead

1920 x 1080 ultra 4x aa

R9 280X CF - avg 115 fps min 84 fps
GTX 760 SLI - 86 fps avg 65 fps
HD 7970 Ghz - avg 65 fps min 48 fps
GTX 760 - 57 fps min 37 fps
GTX 580 - avg 40 fps min 26 fps

applying the 50% scaling which GTX 760 SLI sees, a GTX 580 SLI is likely to run at avg 60 fps. the R9 280X CF is at 115 fps. the HD 7970 ghz is the same card with 50 mhz higher clocks. so you are close to 2x the perf.
