I will list my old system and then the new system. Old system: Amd Athlon XP 3000+ Barton 1Gb PC2100 DDR Ram Radeon X850 Pro Oced to 550 Core 550 Memory. 3dMark05- Max score 5400, default settings. F.E.A.R- Max Settings. Lowest, 16 Ave, 40 highest, 99. Below 25FPS 27%. 25-60 48%. 60+ 25%. Oblivion- High settings 1024x768 Bloom. It ran fairly smooth, until you got into town. Doom3 High 1024x768 2xAA, 47 FPS. New System: Amd Athlon 64 3000+ 1GB PC2100 DDR RAM (Fixing to be Corsair 3200 dual channel) Saphhire X1800XL 3dMark05- Max score 6500. Default Settings. (I haven't figured out why this is low yet) F.E.A.R Max settings. Lowest=23. Ave=68. Highest=127. Below 25=3%. 25-60=25%. 60+=72%. Oblivion, Ultra High, 1024x768 HDR. Smooth as butter. Doom3 High, 4xAA, 8xAF. 59 FPS. (Again, I can't figure out why it's so low, in game it's smooth) Basicly I am seeing much bigger scores with the new system and smoother gameplay to boot. Plus I no longer have to have a window fan blowing into my case to cool the damn Barton. Overall I am happy with the new system.
