D3 has ocing issues, as Carmack has said. People have still done it and you can try too.
Brand: HIS Iceq...good for ocing too.
for D3 more memory is better (doesnt mean the card will be faster) bcos D3 has large detailed textures. With more mem u can have certain maps uncompressed (look below). Assuming ur system is not a bottleneck, I would say a 256 MB is better for Doom3.
You can tweak ur card in D3 to take advantage of 256MB Ram.
" The particular area from very early in the game that Timedemo1 uses isn't painting an accurate picture of overall game performance nor is it showing us the proper differences between the boards. The texture load for the particular area utilized in Timedemo1 is relatively low compared to other areas in the game and while we see the 128MB and 256MB parts performing very close overall for that bench, in game performance on other levels is going to show a significantly larger difference and will likely result in the 128MB parts being unplayable in certain areas, with the 256MB parts playing without a hiccup even though the parts may show identical results in the benches we are reporting here."

High Quality: for 256MB video cards. Uses compression ( DXT1,3,5 ) for specular diffuse and no compression for normal maps. This looks very similar to Ultra quality but the compression does cause some loss.
Medium Quality: for 128MB video cards. Uses compression for specular, diffuse, and normal maps. This still looks really good but compressing the normal maps can produce a few artifacts, especially on hard-angled or round edges.
