Oops 4GB
Just a quick update - purchased a Radon HD 6850 graphics card and upgraded my PS to 750 watts.
It is amazing the difference in the basic display - much crisper (never noticed all of the screws in the instrument panel on the Delta Pony before).
I am now running full advanced graphics (smooth shadowing at 2048) and visibility ranges at full distances while maintaining a FPS of 59-60.
My total investment for graphics card and PS after rebate was right around $200 (purchased at MicroCenter).
A bit of tweaking was required once the hardware was installed (on the 3D effects), however overall the process was very simple.
Thanks again for all the comments and support!
