I want a good graphics card that can run just about everything. I'm trying to decide between a GTX 780 or R9 270. I know that the 780 is most likely way better it's just that I have an AMD motherboard and CPU. Will that affect an NVidia card's performance at all. My current system: MSI 97A-G43 MOBO, AMD FX 8350 CPU. If you have any different card suggestions I'll gladly accept them. My current budget for the card is $600. NOTE: I'm also trying to pick the card that has the best cooling.
