aoa people. i need some buying advice for a gpu card, my budget is approxximtaely 16-18K. as of my research today there are a couple of candidates that i found. sparkle 560(iamxtreme) and the 6850(galaxy). according to most websites 560 is 10-15% faster than the 6850. but i do need to ask that which one should i go for. are there any drawbacks for any of this card. and also will they b compatible with my system. ea500 and asus p8h61m-le. i won't b ove0rclocking at all neither will i sli or xfire. all i need is a reliable card that runs cool and i can sacrifice 10% performance for that.
