Well ,I look forward to the 290x review which ,I have no doubt that upon release ,Nvidia will have a fully unlocked titan ,to release, just to steal a little of the 290's shine .and to bench along side it..

While the memory is faster, the R9 270X still uses a 256-bit wide memory bus and by default comes with a 2GB memory buffer, though 4GB will be an option on some cards despite being pointless for this GPU.
You said the same thing about the 4 gig 670 , 4 gig pointless.on the gpu because it will never be able to use the 4 gig of memory, do you feel the same about them in Crossfire ,or sli, is the 4 gig still useless.?
just asking ,as I have a pair of 4 gig 670's and though I can't bench with 780's. I still love them. play everything at max or near max settings .except for maybe Metro last light,I play BF4 beta on Ultra @2560 x 1600. at near 60 frms...I'm sure that will change upon release.
