+1 for try before you buy
To run games in 3D it is possible to use your existing 5850, however this isn't the best solution as Nvidia do 3D gaming much better at the moment due to their integrated approach. If you were to use your existing card then you would need to buy a monitor or TV that does HDMI 1.4 and supports 3D content (should come some matching glasses), then buy some middleware like tridef or IZ3D.
The "problems" with this setup are the following:
- HDMI 1.4 3D monitors/TVs are expensive and you can't use cheap DVI-D 120Hz monitors like
this (which do work with the nvidia tech).
- HDMI 1.4 only supports 3D at 720p@60Hz or 1080p@24Hz (due to bandwidth resrictions) so you are advised to run 3D gaming at 720p@60Hz. In contrast, Nvidia 3D using a dual-link DVI connection can do full 3D 1080p@60Hz.
- The AMD 3D drivers are written by a separate company - unlike Nvidia where the 3D drivers are done in-house.
Here is some more info on this setup.
As for Nvidia - it has all the benefits mentioned above and we can actually easily spec you a parts list. You basically need a powerful GPU (as 3D effectively halves your framerate by rendering each frame seperatiely for each eye) so a nice graphics card like a
GTX 480 or
GTX 570 (at least) would be a good choice. You then need a 120Hz monitor - and of
these would be great, personally I would have my eye on
this LG. Finally you will need the
Nvidia 3D vision kit (you can also buy
extra glasses separately, but they aren't cheap).
So that is what you need, but I will stress again that you would do well to test out 3D gaming for an extended gaming session before you put your money down.
