Im pretty well versed with most things hardware but my question to the extremers out there is... Will I start to bottleneck if i am running all my main perfs through the PCI bus? Does the 3 slots share one bus? I have a USB PCI card, a Radeon card and now im thinking about getting an ATA card, but im worried that ill start to bottleneck because im pulling so much info from each PCI card, the video and the ATA especially. Am I just better sticking to the built in ata/3 adapter? I'm not used to running video through PCI so this stuff is new to me.
