I bet you like it!
I started to get the 9600 because I built up a SFF box and had considered the possible heat problem with the small box. There is no problem with heat at this point.
At the tme I purchased mine, the 2 boards were about the same price.
No problems with the install.
Be sure & grab the free 3DMark@03 download. Also get the NV Dawn demo & ATI patch to run it.
