hello guys and girls it is just about time for me to upgrade my vid card because the card i have finally died on me (nvidia Geforce 7600 GS) i went over to new egg thinking this would be an easy task finding a new vid card but little to my knowledge it seems like alot has changed since i bought the 7600gs so i have a few questions and just so u know i game on the pc so i need the card to be able to handle things such as call of duty modern warfare 2 and battlefield bad company 2

1:what is the difference between the cards as far as GDDR2,GDDR3 and GDDR 5

2:As far as the memory on the card goes if im gonna buy a new card i want to buy somthing with more memory than my previous. So i want to try to get either a 512mb or a 1G

3:Is there anything else i should look at on the card such as core clock, memory clock, and shader clock speed

here are some of the cards i have been looking at that are in my price range unfortunaley i have to stay at about 80$ (i want a card with a HDMI input)

GDDR3 is about twice as fast at the same base frequency as GDDR2, and GDDR5 is about twice GDDR3.
GDDR2 cards are fine for 2d, but i wouldn't get one with the intention of 3d gaming.
Bus width is important too, 128bit gddr5 is the same as 256bit gddr3, or 512bit gddr2, again given the same base frequency.

The GT240 for $80 is an excellent price/performance spot, nothing i can find can touch it.
However, for $14 more you get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102824
Which will stomp it.

The GT240 is newer and runs cooler, and so should be quieter at full load. At partial load or on the desktop i doubt you'll hear either one.

wow man that card is a beast and is not bad for that price read some of the reviews and so far have read nothing bad my only concern would be that car is compatible with my motherboard and is my powersupply strong enough to hand that monster =]

PSU will be fine, it's only a 110w card so your 750w PSU from a totally decent company will handle it without an issue.
I'm assuming the motherboard is PCIe, in which case it'll slot right in and haul for you :D
