Need help choosing my first GPU???

[kylo]

I am looking to spend $60-$100 on a graphics card at newegg.com
This is pretty much the best game i will be running http://www.totalwar.com/empire/?t=EnglishUSA

This is the mother board i have......
http://www.gigabyte.us/Products/Motherboard/Products_Spec.aspx?ClassValue=Motherboard&ProductID=3143&ProductName=GA-MA785GM-US2H

I have picked out these GPU's they seem to be pretty good??? The second one seems to have faster speeds and its cheaper...
(is there a way you can check if the card is compatible with the MOBO or does it just need to be a PCI Ex16)
Radeon HD 4830 512MB -- $99
http://www.newegg.com/Product/Product.aspx?Item=N82E16814102822
Core Clock 575MHz
Memory Clock 900MHz/1800MHz
Memory Size 512MB
Memory Interface 256-bit

Radeon HD 4670 512MB -- $70
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125244

Also does anyone know what the sound lvl of these GPU's are?? My computer is pretty quiet so i need a GPU to match it.. (if possible)
I play mostly strategy games..!! (controlling tons of troops and stuff like that)
resolution is 1680x1050
Right now with the on board video (ATI Radeon HD 4200)

What power supply do you have? That is likely to be a limiting factor. Graphics cards require a power supply with one or two PCIE power cables.

i have a 4830 in my media center its pretty quiet, im fairly confident that my 120mm fans are louder than that if you leave the fan at stock settings.

 

[ik694]

Once you start using the fan control in CCC it could get louder but still no where near intolerable like my 4870x2

Also might want to look at the 1gb variant too its only like 2 or 3 bucks more, or at least that was the case when i got mine

The 4830 will be enough for your gaming needs. I do not believe the card is powerful enough to use 1GB on higher resolutions, so just stick with he 512mb version.

However, here is a better choice, a 4850. The 4850 is a tier above the 4830 and equal to a 9800GTX/GTX+/GTS250:

On newegg it's $99, and $89.99 after MIR

The 4850 requires a single PCIE power cable and a 500W power supply. If the power supply is cheap junk he wont be able to add a good graphics card like that.

A 4830 also requires a single PCIe. The 4850 uses slightly more power, but if he can run a 4830 then he can most likely run a 4850 as well.

Either a name brand 400watt PSU or a cheap-o 500watt PSU should do the trick.
