if someone could give me specs again with all arguments with better parts and that ?
What are you asking for? It's not exactly clear.
And it's not likely you'll get total agreement on any one single configuration - especially with fairly vague objectives like "
i want a pretty killer computer". You're asking for an attractive looking, powerful computer, right?
One person mentions that you don't need a powerful graphics card for a 3d rendering and animation workstation and another says you want a powerful graphics card to assist in rendering and animation. Both are correct - depending - on what software packages you will be using, and how you use them. You haven't provided enough guidance or information to know which is the better solution for your system. Knowing your budget is always helpful and you were good about that. But I get a definite vibe that you'd like to spend less than $3500. So it's important you state what you REALLY want to spend. And maybe what you're willing to spend if it can be shown to be worth the extra $$$ spent.
Spending $1000 for a 3.2Ghz Core i7 965 is an option. And so is spending $290 for a Core i7 920, $70 for a CPU cooler and overclocking the i7 920 to 3.2Ghz.
A Gigabyte X58-UD3R motherboard was mentioned to save $50 and it's a good motherboard. But it will limit the amount of RAM you're able to install compared to ASUS P6T, ASUS P6T Deluxe or Gigabyte X58 UD5 also mentioned. X58-UD3R supports both dual channel and tri channel DDR3 modes so you'd have the option of using 2GB/3GB/4GB/6GB or 8GB of DDR3 RAM. The other MBs are tri channel mode only and you'd be able to use 3GB, 6GB or 12GB using the most commonly available DDR3 RAM kits.
I'm guessing you're not a full time graphics/3D & animation worker. They usually ask for a system that will run specific software packages. And they usually have a better idea about what core components they need/want for their software of choice, usually from hanging around the software forums where the other graphics/3D & animation workers hang out.
Do you know what software you'll be using? Are you going to be making your living with the new workstation, or is it for more of a hobby or educational experience? Are there any other software packages you might want to try during the lifespan of this workstation? Have you visited the software forums to get an idea what hardware works best with the software you want to use?
How many hours a day will you be using your workstation for heavy 3D & animation work? Someone mentioned you might want a better monitor.
Will you be thinking about resale value in the future? How long do you expect to be using this new system?
It's going to be your workstation, and it's your money you'll be spending. It's a good idea to take ownership of the process and do enough research on the software you'll be using so you'll recognize the best options. And maybe be better able to explain your requirements or expectations for your new system.
