I would like to up grade my video card from a evge 8800gt to a evga gtx460. The question I have is which gtx460 card to choose from. The budget I have is around the 150.00 area. Fsx and rise of flight are my main flight simulators along with cfs2 and wings of prey. The cpu I am using is a e8500 overclocked to 3.4 ghz. Thank you for any help.
