I just recently became the proud owner of a new Mac Pro, but was disappointed to find out how poorly the NVIDIA 7300GT video card performed. Basically I was wondering what my best option would be for a video card would be. I did a little research and read that the options were very limited (between the 7300GT and an ATI Radeon I believe). Is this true? If not whats the best video card I could possibly get that would be compatible? Thanks in advance
