i thought i knew about graphics cards and that the way to see which one would be better in comparison is basically just check the VRAM. i think i'm wrong. i would love some info. here's why: i have two cards in my machine, i'll spare the whole backstory as to why. but one is an ATI Radeon 9200 mac edition with 128mb (i had purchased it because it had an s-video out so i could watch on my tv) the other is my quicksilver's original oem AGP card, an NVIDIA GeForce2 MX with TwinView. In system profiler it says it has 32mb VRAM. HOWEVER, it outperforms my Radeon by alot. using backlight 2, and comparing how it looks on either screen is a VERY NOTICEABLE difference and the NVIDIA is CRUSHING the ati but only has 25% of the vram as my "performance" ATI card. Even on blu-ray ripped movies (which my machine cant really play satisfactorily) the ATI stutters and lags while the NVIDIA just seems to drop a few frames here and there. WHATS GOING ON? also if anyone wants to offer advice or directions on overclocking the ATI Radeon it would be appreciated.
