It'd be a waste to buy an 8800ULTRA. Quadro graphics cards aren't for gaming either.
With your processor the max you will want is an HD4850/5750 or a GTS450.
GTS 450 is fit in my pc or support.
Which is good Card for me Quadro 600 Or GTS 450 .
PSU 450 W , AMD Athlon 64 X 2 5000+ 2.60GHz , Mboard ASUS M2N68-AM, 4 GB ram &
my budget is 8k to 10k in Indian currency.
I need Card For Rendering In Maya.
