I have a GA-990FXA-UD3 mobo and i need to update it so i can upgrade my CPU to 8350.

I tried to install it from: http://www.gigabyte.com/products/product-page.aspx?pid=3894#bios

but it says i have an incorrect version (64-bit instead of 32-bit) and I cant find the 64-bit version anywhere. What do I do?

You can update Bios in Many ways, one thing is after updating bios, your may face some minute problems like getting strucked, slow performance..etc beacuse I faced these problems after updating my ASUS K8V-MX motherboard, well I did got some other problems like capacitors failure after I came to know that this problems came into existence because of failure of BIOS. But I am not sure about the problem caused beacause of updating BIOS.

http://www.gigabyte.in/products/product-page.aspx?pid=3894#bios in this link you might be choosing 32bit operating system, downloading the exe file but check which operating system selected by you and download the exe file and follow the on screen instructions. If same problem persists there might other ways to update BIOS.

So I'm not very good with computers. And I'm not big into gaming, so I really have no idea what to look for. I'm buying it for someone else, since my mom can get it for very cheap through her work.

Can anyone tell me if it's good or not?

CPU: Intel i7 3770 3.5GHz

RAM: 16GB DDR3

HDD: 320GB SATA

Video: Nvidia 1GB

Like I said, I'm not good with computers, so if I'm missing any info I apologize.

Intel i7 is excellent processor, as 3770 is a 3rd generation processor and I found there is lot of performance difference in the 1st generation and 2nd generation. You have choosen good processor as it is 3rd generation. Better go for Intel i7 3770k you can unlock the processor speed upto 3.9ghz. Better install a cooler master Thermal Solutions when you installed with 3770k.

You didn't mentioned motherboard, choose a motherboard that suitable to processor, best is Intel Z77 express chipset choose from the best makers like Gigabyte, Asus, MSI as per requirements. My opinion is go for Asus SABERTOOTH Z77, it is very good in performance, if you need more specs click here

You didn't mentioned whether the hard disk cheetah, baraccuda, SSD. Choose SSD's there will be a lot difference between normal hard disk and SSD's. Transfer rate will be more in SSD's than compared to normal harddisk.

Nvidia 1GB, Make sure which model you are going to install, if you mention the games which you play I can give the list of graphic cards supported by that games. Make list of games, then choose the better graphic card.

As you are installing 16 GB DDR3 of memory, you need install 64bit operating system.
