Hey everyone, I bought my 15" 2.44 ghz i5 MBP about 6 months ago and noticed it was running quite slow. I have never been very computer savvy and had nothing to compare it to until just recently my friend bought the 13" C2D 2.66 ghz MBP. Mine is running much slower and scoring 51 on Xbench while his is scoring 170. My fan is constantly on and it struggles to load up videos and programs. It's just slow in general. I had it wiped because Kernel task was taking up 270% of my CPU usage and it's still slow. So I took it to Best Buy and they are telling me that it's running fine and the fan is supposed to be always on. Any advice on what I should tell them? Are the 2.44 i5 just slower than the 2.66 core 2 duos? It starts up and stays at good speed for about 15 seconds after sleep then gets slower, any advice on this? Your help is very much appreciate.
