im about to buy a sony vaio notebook but i have to choose between i5, 4g ddr3 with NVIDIA GeForce GT 330 and i5, 4g ddr3 with ATI Mobility Radeon HD 5470 Graphics (512MB VRAM). which do you think is much better guys? im not much of a gamer but i want to install this with World OF Warcraft. the price is not a problem since theyre pretty much the same. thanks.
