Pros: Faster than my old 32bit XP box with a single processor. Can run 64 bit programs now which seem more efficient. Set up was a no brainer. Plug it in and go. Cons: I thought a computer like this would be very fast considering what it contains, but the hard drive seems slow to access and process files and opeing folders. For 6 cores and 7200 ATA drive, I expected more 'blazing' speeds. The biggest thing I'm upset about is the fact that in a box like this they only put a 300W power supply. I have some software that disables features on this ATI Radeon card because it's not compatible with background drawing and scene antialiasing for 3D rendering software. So I now have to replace this card with an Nvidia card, but the one I need doesn't support anything less than 400W power supply. So now I not only have to buy a new graphcis card to run my rendering program, but I have to have the power supply upgraded as well. I'm not a gamer, but if you look at this computer for gaming, be very aware that if you want a better graphics card you're also going to have to upgrade the power supply. I run lots of 3D graphics, modelling and rendering software which is not running that well with this ATI Radeon card.
