IMO it's not really about the graphics cards -- it's about what you're showing (the action, the composition, etc), and yours have PLENTY to offer!
Thanks guys, the one I most wish had turned out better is the 3rd one down. Took the p40's right wing as he rolled over the top of a loop when he was trying to get guns on my dad. I was visiting my parents home and so my Dad and I were in the same room on different computers flying FSO, we both got shot down before the end of the frame but it was made all the more fun because we were sitting next to each other during the event. (he got up and grabbed a new beer for me right after clearing that p40 of his six )
That sir, is priceless. I am very jealous of you.
There must also be a flyable computer available for Nefarious to do FSO. So he doesn't keep talking about it for eight and a half hours on Friday night!
