Looking to purchase a new desktop for gaming and 3D rendering, flash content and after effects. Out of Dell XPS 7100 or Dell XPS 8100 which one is a better buy. Dell XPS 8100 has a GTX 260 which doesnt supports DX11 while Dell XPS 7100 has ATI Raedon 5870 which supports DX11.
Yes, instead of buying prebuilt systems, you could build a much better system yourself for the same price; or build the same system (as the preconfigured) for a lesser price.
Anyway, amongst the two, the Dell XPS 7100 would be better
