Is clock speed more important than memory size in a graphics card?

[Malek Agha]

Right now I am stuck between the Radeon R9 280 and the EVGA GeForce GTX 660. They both have the same stats, except that the EVGA GeForce GTX 660 has more clock speed; but people say the radeon R9 280 is better overall. Can someone help me out and tell me which one is better?

Neither are the most important. For graphics cards, the shaders, bandwidth, ROPs, etc. are more important. Basically, just go off of benchmarks. At your price point, I would suggest an R9 285, or, if you can pony up for it, an R9 290 or even a GTX 970.
