naa, not there, poor exaple pehaps, but i see them all the time, espiclly on ebay, look up 512mb graphics card, theres always loads goin cheap, just wondering why?

hmmmm, interesting, so what makes a good card then, lemme get this right, a graphics card has its own cpu and memory, so one of those VGAs would be like putting 1gb ram in y mobo, with a 400mhz P2, when you want a p4 with that gig, right?, how can you tell how good the vid card is then?
the GPU is what makes a card fast
first, you want to look for a card with more pixel pipelines. the more pipelines, the more it can render at one time.
also, the higher the clock speeds, the faster the pipelines render.
Cards with 512 MB would have to have a powerful GPU. This is because only a few things use up more then 256MB of VRAM, and in order to get the settings that use more then 256MB you have to have the settings jacked WAY UP. Maxing out games like FEAR, Doom 3, and Quake 4 on high resolutions (which uses around 300-400MB of VRAM) will kill a 512MB 6600GT or a X1600.
Look at the GPU first then the memory. But the things you should look for when looking at memory is:
Type of memory (you want GDDR3)
is it 256-bit or 128-bit?
What speed is it?
How much of it is there (128, 256, 512)?
Most new games on high settings on normal resolutions like 10x7 and 12x10 use around 100-140MB of VRAM. Therefor I recommend that you get 256MB. 128 is starting to reach it's cap, but 256 is fine for now.
