Well, its that time of year where Nvidia usually chucks out a test piece hardware on the public in their budget line.
whether that be a improved version of the KEPLER series cards to replace the more dated first versions such as the 5 and 6 series cards (that had no kepler GPU) mainly to include GPU Boost and 28NM technology with more efficient power consumption with more added memory to the budget cards, not that that's exciting nor does it bring a better experience to the budget buyers, its still a budget card but these features make them more fluent and smoother in their rendering capabilities, plus more compatible to those who have low rated power supply making room for competition in the budget build market where it seemed AMD-ATI had a little more than a fair share when it came to choice. That's my opinion its not fact and open to debate with many readers.
as of 18/2/2014, it seems Nvidia launched (quietly) a replacement to 5 and low end 6 series kepler gpu cards, with the 750 and 750TI 2gb in the new MAXWELL GPU line that will get ready to replace the kepler in the next 2 years.

now this is strictly a budget a card line at the moment, don't expect anything exciting just yet they are still 128Bit (down from 192bit to save power consumption)and 28NM tech cards, the good news is that they are DX11.1 giving those who have windows 8 and 8.1 direct fulfilling graphical experience to the OPSYS where low end budget cards would have some issues in compatibility often prompting you to use a more "basic" windows theme, then next bit of excitement is that reviews boast great overclocking potential due to its low power consumption overhauled memory (and if you read the reviews the clever bit is with its memory distribution and shared compare and swap (CAS FOR SHORT)32bit to 64bit intergers which the kepler GPU started to give us a look at briefly with the 780 and titan) and an increase in cuda cores over the previous budget lines brought to us.
Why is exciting to gamers to see a budget card come out? well i'll tell you. its possibly the foot print in the sand to great mid to high end gaming rigs in the near future, the Maxwell is intended to reduce power consumption over older lines, meaning SLI wont require a stupidly expensive PSU to power 2 cards or more, the Maxwell may feature a ARM CPU/GPU type chip which should see it operate more independently of the main CPU also with the new memory infrastructure and architecture there should be a an increase in l2 cache sizes perhaps 2MB as supposed to 256Kbts and we could see a trend of 2GB-4GB memory size cards instead of 1GB or 1.5GB.
what would this mean, it would mean that GPU to main CPU bottlenecking a thing of the past, it would mean that the GPU would talk more efficiently effectively and smoothly at a faster rate under extensive load and be completely indapendant under normal and mild load at lower core temps. it would mean that although a CPU being fast and expensive will help in GFX processes and renderings the new ARM maxwell GPU should take this on its own meaning those who do not want to spend 200+ on a cpu to take the slack up in heavy GFX processes can now breathe a little sigh of relief that their wallet isn't going to suddenly lose weight. it would also mean a leap in terms for laptop users, and mobile media applications.
in some years to come perhaps 2 or 3 we'll see NVidia's volta GPU wich boasts a stacked DDR memory type, introduced this way.
so while it may be were 12months or so away from NVidia releasing the 6 and 7 series Maxwell replacements for the kepler lines, I think its well worth watching the market this year and holding off on a big GFX card purchase, as son as these lines are released then kepler series cards will decrease in price.
