Hello everyone. I have a question for you all. I purchased Dell's new dimension 8400 for which I chose all the components to use. I had $1500 to work with so here are the specs: 3.0 Ghz p4 with HTtech. 800Mhz FSB; 512 MB of Dual Channel DDR2 SDRAM at 533 Mhz. 128MB PCI Express x16 (DVI/VGA/TV-out) ATI Radeon X300 SE video card. My question is why, when I run Halo for PC, does it still hang a bit on the highest settings? Also for Hitman Contracts? Admittedly, it performs much better than my old p4 1.6, but I assumed that this would take care of any hang-ups? I would appreciate your advice, Thanks! Buff.
