I'm in the market for a new card to replace my GTS250 that came with my computer. Originally i was in market for something under $150 and figured i would get a 1GB GTX 550TI. However I decided to spend a little more and now looking at GTX560.I have found a 2GB GTX550-ti in the same price range as the 560, the question i have for all the experts here is which card would give me the best performance in FSX? Will the extra Gig on the 550 really help or am i better off going with a GTX 560?here are the cards I'm looking at.http://www.tigerdire...6682&CatId=3669http://www.tigerdire...p?EdpNo=1308178My basic system specs are i5-270 2.0ghz w/4gb ram. and 650w PS.

I´ve been it the same situation as you! I tried to make the change from the GTX 260 and also thought about the 550Ti as well. But finally after a certain ammount of consideration I settled with the EVGA GTX 560 SC 1GB. It´s an standard 560 but factory oc to 850 MHz and from what I can say it´s an awesome card for that money! My GPU usage is rarely over 60% when Ffying with the NGX and having an perfect AA setting. Hhe IQ is the best I´ve ever had. Also the card is wonderful quiet and cold (Only 55°C max in FSX).And for technical terms, the number of steam processors and the memory bandwith are what really counts. And this numbers are much higher on the GTX 560 SC than on the 550TI
