Hello people, here's the thing. After doing a little research I decided to buy an Ati 4670 for my second PC to play LAN games, It has the following settings, intel e5200, 2GB DDR2 800MHz, 19inch LCD monitor. The thing is there are ddr2 and dd3 versions of the card, and 512m and 1g versions.. is it worth to pay 20$ more for 1g ddr3.. cause i need to buy a new PSU, ati support says i need a 400w and i have a 235w psu. Thanks in advance! i'll wait for your replies
