All indications is Kepler due out March 18-30. GTX 670Ti and being projected greater perfomance than a 580 and 7950 for $300.
Now the perfomance speculation I can belive but the price I find it estimated to low and hard to believe.NVIDIA Kepler “GK104″ GeForce GTX 670Ti Arrives in March 2012, Performs better than GTX 580 and HD7950
I'd hold off if you can. If not an EVGA GTX 580 3GB Ultra Classified
for $549. It can hit a 1000Mhz Core easily.
Personally I'd wait but if your build is ready then waiting four weeks can be an eternity. I'm asumming since your posting in the Nvidia forum an AMD is not optional. Ive had AMD for years and I'm not going back being happier with Nvidia as a personal preference so I could understand.
If you do decide on the 7970 it's a lot of perfomance for $570, very good card. As for the 7950 you can pick up a EVGA GTX 580 1.5GB for $449
currently after MIR for same performance/price without having to switch.
Good luck. Edited to add
- Wait I just noticed your monitor is a Samsung 120Hz? Which model number? I ask because with AMD at least you can get the full benefit from AMD HD3D
. It's not as good as Nvidia 3D Vision monitors for 3D Vision but you might as well utilize your monitor to it's full potential. If that's the case and you have $600 for the budget then by all means take advantage of the 7970 GPU instead.
