Building a new system and was going to order the 7900GTX card but newegg is showing about 8 or 9 different 7900GTX. Now I'm really confused. I want a good card for primarily gaming with some ocassional CAD use. My PSU will be the Hiper 580 unit. Anyone help me narrow it down. The ATI cards look nice too, but a little concerned with the noise & heat issues. I am looking for something in the $ 350.00 to $ 450.00 range. Thanks
