So I've been looking at upgrading my Nvidia gtx 550 ti here recently and budget has lead me to these 2 cards. I'm pretty sure either of them would be a noticeable upgrade in my system but just trying to figure out which would be the best for me. Also I've never had a Radeon, I've nothing aginst them just have always ended up with Nvidia. Mainly what I'll be pushing them with is WoW: Mist of Pandaria, Diablo 3, and prolly Call of duty black ops 2 soon just to give an idea.
As of now I can pretty much run wow in the new higher demanding content around 40-60 fps on high settings would like to achiev Ultra settings with this upgrade as well, I'll list some more info on my rig at the bottom.
Also I've noticed the gtx 660 ti is on a 192 bit memory interface like my 550 ti but the radeon 7950 is on a 384 bit memory interface was kinda wondering where all that stuff comes into play as far as performance.
Also I will be using MSI afterburner to OC which ever one i get a little bit, probably not going to mess with voltage.
Thanks in advance for your replies and let me know if you have any questions for me.
Yea they seemed pretty close when I was looking up benchmarks on them. One concern I have is the Radeon's software like drivers etc compared to Nvidia. I guess what I'm saying again is I've never owned one and wonder if I can expect better, worse, or on par with Nvidia in that department. As far as the hardware they seem to be almost equals.
