Since Halo is mostly a GPU intensive game I would like to know what graphic cards you have used Halo with as well as the rig (CPU, motherboard, memory, etc) I also heard about Halo being able to run with Matrox Parhelia graphic cards but have not see actual screen shot proof. That is really interesting since the Parhelia is capable of Triple monitor play and I am hoping that Matrox eventually makes a new more powerfull version of the Parhelia. My rig that I tested Halo with is PIII 1Ghz, Intel VC820, 512MB PC600 RDRAM ATI Radeon Fire GL 8800 128 AGP 4x workstation card. The game runs fairly smooth for gamplay with occasional stutters here and there but its very playable for me, also multi play is smoother, however I have not ran the benchmark yet. I have not yet tried it in my alternate rig with the G400.
