Last one is more brightness and more realistic the first one. good job..

Gtx 580 is good solution. But not enough!! Because other helpers (like photoshop, ae, premier pro etc..) use cuda (opengl) for speed and performance!! So i think u have to use minimum Quatro 4000!!! I want to use gtx series 'couse these series is the performance series, powerfull series but their driver does not fully support for using cuda microprocessors SO!!!!!!!! you have to take a Quatro series like Quatro 4000

There is a lot of reasons... So if u can do, you attach any screenshot or give more details regarding this problem!!

Actually its simple, only click and turn off gamma button (sometimes it may be overlooked) Details: When you turned off this button, SR leaves the control of gamma setting to user. Then you can change this setting like you wanted, under "Rendering > Gamma/LUT Setup> Gamma"

I think you use SolidRocks plugin? If you use this plugin, you have to change some settings in options menu as it gamma. Because SolidRocks trying to take the control of render settings.
