Summary: I really can't rate the base machine as I had numerous modifications made to it (SSD hard drive-the original is now where the CD Drive was). But this is a very good, quick and quiet(ssd drive) machine.
Summary: Replaced DVD drive with a 1TB hybrid drive. Installed Windows 8. The combination of processing power, memory, and disk space allows me to run multiple Hyper-V servers in my virtual lab. Bought a SDHC flash drive to enable and use Readyboost. But the performance utility in Windows 8 tells me I don't need Readyboost with this machine!
Pros: Very powerful notebook. Processor is great, very responsive with about any app or with multiple apps. FAST bootup and responsiveness with SSD.
Cons: Heavy; battery life not great. The price you pay for a mobile workstation.
Summary: I originally bought an HP 4545s that was on sale for ~$400. I received it, and while updating it, the motherboard ended up getting fried by a failed BIOS flash. Well, they had no replacement 4545s' in stock, nor a replacement motherboard for it. Instead, I was offered a 8570W as a replacement\upgrade. I could not be happier. I have had this laptop for a few days now, and it is spectacular.
Summary: At first, I was skeptical, but i got the computer anyway. Now, generally I'm a mac guy, but I wanted to start playing pc games in my free time and traded to this. Games Like the new Tomb Raider, and Bioshock Infinite look unreal. I didn't even know laptops could produce graphics so powerful. Of course the 256 ssd drive is nice too!
Summary: Early versions of the laptop had issues with the motherboard and/or video card. Laptop would reboot on its own 5+ times per day when I first got it. HP sent out a tech and took a few visits but eventually they replaced most of the parts for free due to the onsite warranty and since then it has been rock solid.
