Hello everyone! First post, can't wait to pick your brains! I decided to upgrade my processor from an AMD 3800+ (2.0GHz) to a 5600+ (2.8GHz) because my CPU frequently max's out when I'm multitasking, and vids get choppy. Computer booted up fine, drivers installed successfully. I rebooted, and noticed that bootup actually takes slightly longer now?!?! Also I don't find that my app's are starting up any faster really. Every thread I read discussing similar upgrades resulted in huge improvements, and so far I am not impressed. What do I do? I also noticed that when app's start up, the processors are running at like 10-20% (fluctuates). Shouldn't they work harder and open up app's a lot faster? I'm assuming there's a bottleneck somewhere? Thank you in advance for your help, I'd be happy to answer any aditional q's. I ran Everest diagnostics on comp before and after CPU switch just for fun, so have lots of data (I think) P.S. core's running at about 25 degrees C at idle, up to high 30's when workin moderately. In case it doesnt post with this thread, I have a dell E521 (Geforce 6150 MOBO), with 2 GB 667MHz RAM, 2x 250GB HD's @7200rpm, Geforce 7300LE 128MB, and currently have the stock 305W PS, but have ordered Coolermaster Extreme 650W PS, should get it in next few days.
