Taken from anothe thread, which i posted in I recently made a thread( which i hope the admin deletes soon ) about how i thought i needed a new PSU, because for some reason my external HD, which is 500GB was putting a strain on my hardware and it didn't help , because i am using 90watts. So come to find out, well first i have a USB high speed 2.0 Pci card in my tower, and i had my external HD hook up to it. That was putting a seriously strain on my computer, i didn't even know it was doing it, until i restarted without it being plug in and played a game. So now i have the HD hook up to the back of my computer, which is a non 2.0 high speed port. Here are benchmarks , only tested out one game so far, but man this is amazing: Shade Wrath of angels 1280X1024 Max Settings( NO AA, option is not available) w/ HD hook up to 2.0 PCI card = " 12-50 " Meaning, it starts at around 25, just standing there looking at a wall or in a inclose area, but once i start moving out in the open or fighting, it drops to 12 " 1280X1024 Max Settings( NO AA, option is not available) w/ HD hook up to my tower " 30-80 " It doesn't struggle anymore lol, and i can move around and fight and it will stay at 30-45, then quickly go up to around 70-80. What i don't understand, how come when the external HD is hook up to the USB 2.0 card, it puts a strain on my computer, but when its hook up to the back of the tower, it doesn't? What do you guys think? This is awesome. Going to test out more games. EDIT: OMFG, GTA 3 IS running at 70-100fps now, i use to get 30-50. OMG LOL This is amazing. I am going to download Crysis demo and see how it works. I tested out 5 games so far, all 5 of them at max settings, no lag or anything, i didn't even know games move this damn fast hahaha. If i would known this, i would of never put the external HD in the usb 2.0 to began with. Its not like nothing is holding back the game anymore, its hard to explain, but damn. ............................................................ Someone said i might of had a irq conflict. Its like i got a super boost in gaming or something, there is no more bottlenecking in games, none of that you know, frames dropping and pausing mess. This is amazing, i didn't even know my p3 can move this fast. Its like my 2400HD and CPU is being use at its full potential. So everyone, check our hardware , make sure nothing is hold it back.
