Graphics card memory

[WatchTower]

The main thing I read graphics card memory is for is giving better res. What I wanted to know what other things does it effect? I was just wondering so in future I can make the right choice in what cards I should buy.

Thanks

I was thinking of getting a 512mb card you see but I only have a 17inch LCD monitor thats why I wanted to know.

In general the more memory a graphics card has - the more details you can turn up - ie the higher the settings that you can use.....

BUT, as someone already said - if the card isn't good enough to produce decent frame rates, with the details turned down - then it is a waste to have the extra memory, because you'll just get even lower frames if you turn the details up!!

I've seen a 512mb 7900GT here on OcUK which looked fantastic value I think it was around £270 thats what got me thinking.

Would there be any probs putting a 1800 XT in an SLI mobo if I'm only using a single graphics card?
