Wow I just had sort of a personal GPU revelation
I just poured over some of the benches on Toms 2012 chart
http://www.tomshardware.com/charts/2012-vga-gpgpu/benchmarks,135.html
now granted drivers have matured especially for the 7970 but this is eye opening
I looked specifically a 1920x1080 performance
I looked at 3Dmark 11 performance,Unigine Heaven performance,Metro 1080 and Crysis 2 1080
what i realized that is at 1920x1080 the following cards are within about 5 FPS of each other
7970,7950,660Ti,670,760,770
really they trade blows back and forth
there are instances in those benches where a 660Ti is beating a 7970 or 7950 beating a 770
funny thing is they are all generally around the 60 FPS mark at performance 1080 settings
so really at 1080 all that matters is price
at a 5 FPS average difference across a variety of benches it doesn't seem to matter
heck on one bench a 650Ti SLI was beating a Titan LOL
really if you selectively use a few benches you can make almost any similar performance card look better than another
I would have to say right now the smartest choice in a gaming card is the 7950 at its new price point if you are gaming at 1080 and gaming is all that matters
arguing over a difference of just few FPS is sort of silly isn't it?
