I am looking to buy a new graph cs card but I am not sure what to look for to tell if one is beeter than another. The two cards I am most interested in is GeForce GTX 650 Ti 2GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card or Radeon HD 7850 1GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card OC Version. What I dont know is which one is superior and why? The geforce has only 128 bit memory but a much faster memory clock and amount. So please which card is better and why?
