ATI or Nvidia?

First topic message reminder :

hi mga master get ko ulit advise nyo..
my purpose: for CG rendering and anim., multi tasking)

my choices:
Nvidia GTX 275 896MB DDR3 448bit HDMI
or
ATI Powercolor HD5770 1GB DDR5 HDMI

which po is better?although mas mahal ng konti ung GTX, pero pasok parin sa budget.. nsa 10k kasi budget..

pakonti konti ng nabubuo ang CPU na inaasemble ko, (thanks to CGpinoy mas namura pero mas gumanda ang specs)
as of now nkaorder na:
intel core i7 930
Asus extreme motherboard (hindi ung rampage)
8 GB Ram
1t western HDD
1000w corsair power supply
optical drive
cooler fan

kaso wala pa casing at video card,
pero may choice na ng casing..

thanks and Godbless

hindi lang, yung quadro5600 mga 130k~150k pa nga.

^ yup, alam ko mga ganun nga presyuhan nyang quadro. baka yung 30 to 40k second hand na or quite an old model.
