Hello, I just recently purchased two video and I am assuming that one is better than the other but needed some professional advice. I purchased a MSI n250GTS 512 mb GDDR3 and an HIS ICEQ 4670 1GB DDR3. Now I am not running in super high resolutions so I understand that 1GB is not necessary. However, the MSI is an underclocked 250gts and the 4670 is overclocked I believe. I know the 250gts is a better card normally but in this case is that true?
