128MB vs 256MB - is there a difference

My question: 1. is there a performance difference in 128MB and 256MB cards? There are other questions, but I'll ask them later in this post.

Some benchmarks would be very helpful in this thread.

I know that cards with extra memory (256MB, 512MB, 500,000GB in 2020, etc.) can access texures very quickly, a-la-doom 3 and its "recommended" settings, which include: Normal, for 128MB cards, High, 256MB, and Ultra, 512MB.

I have tested my Nvidia 5900 (AGP) 128MB card on high and ultra @ 1024x768. It can run Doom 3 with these settings, but it still looks like crap (High performance mode & no AA/AF). It also stutters like satan himself is urinating on my video card.

2. If I were to use a higher MB card, would the stuttering go away, or improve?

As technology rolls onward, so do the speed of video cards. 3.Considering my 5900 stutters a lot in High and Ultra modes in Doom 3, would a faster 128MB card, like a 6800GT, or a fast ATI (Are any of the ATI X800's 128MB?) get rid of the stuttering, and would the improvment be as good as a 256MB card?

This one should give your brains some stimulation. :p

I'll search for benchmarks, but a 128mb card that is of better quality will always trump a 256 last generation card.

agreed. In todays games 128mb is enough. E.G if u compare a 6600 with 256mb to a 6600GT with 128mb the GT will whoop the standard.

I read sumwhere about the 512mb 6800Ultra vs the 256mb and in alot of tests the 256mb was better.

Well you just cant go comparing memory

The reason why the 6600GT wins is it's pipelines, and core speed
i was wondering the same thing when i was purchasing my GF4 Ti - whether to get a 64Mb or 128Mb version. i think it was like 3 years ago. Luckily I got the 128mb version, even though the performance difference was quite insignificant at the time. Nowadays I can still use the card (im getting a new one "soon") and even reasonable-resolutioned textures.
