Overall performance isn't that amazing. But performance per watt is really, really good. Especially considering it is still a 28nm GPU.
This. Almost every poster before you is cheering the improved performance/watt but neither card is moving the
absolute performance much. I only care about performance/watt in how it translates into mobile/laptop gaming since in this usage model there is a limited PSU with the laptop and severe cooling and power constraints; and to forecast how amazingly powerful the GM210 will be. In that sense, based on perf/watt of 970/980, I am stoked for the big daddy Maxwell!!
980 is beating 780TI but it's clocked at 1216Mhz and 780TI is crippled by 928mhz stock clocks. What happens when both are overclocked to the max? 980 doesn't look so hot as a marketed next gen flagship successor performance wise even when 980 is clocked to
1.45Ghz. This really is a 960Ti/970 at most.
^ Based on overclocked results, 970 becomes a sweet spot value. I think I'd spend a bit more and get 970s over a single 980.
As far as 980 beating 780Ti by 13-15% for $550, that not even remotely impressive esp. once both are overclocked where 980's performance seems to approach < 5%. 13-15% faster at stock also changes little about the overall playability factor for those who held off upgrading to 780Ti for 1 year. Sadly this is also the
lowest generational jump from x80 card to x80 card in NV's history, which honestly makes me question the 980 branding. And it isn't as impressive as 680's jump over 580 which was the 2nd lowest in NV's history as far as generational jumps go from x80 card to x80.
I'd take a 60-70% faster 250W GM210 all day over a 980 even if the 980 used
100W of power. If I wanted to get the most power efficient gaming setup in my living room, I'd get a Wii U or i3 + 750Ti and brag all day. But at least NV is going to give people options with mid-range 970/980 and flagship GM210 down the line. Options are great for the consumer.
My 1000W SeaSonic is ready for dual GM210. The dollar jar is being filled in anticipation. :biggrin:
*** I can see people hitting 1.5Ghz overclocks with 980 Lightning / Asus Matrix cards which has me even more excited for what NV can do in 12 months with GM210.

TL; DR
1) I am super impressed by NV's improvement in Performance/watt on 28nm with Maxwell -- amazing new architecture;
2) Still longing for a much faster performance increase over my 7970 OC than 780Ti OC /980 OC. Come on NV, give me the large monolith flagship for at least 2x the performance!
3) 970 OC looks sweet; the performance/$ proposition for 980 looks to fall off a cliff when both are overclocked. If 970/980 pricing is $299-349 vs. $549 for 980, I'd pick dual 970s without question.

Colorful 980's PCB/circuitry looks beast mode for 1.5Ghz air cooled overclocking.
