Well, kinda, I moved from a Dell Dimension 4700 with DDR2 RAM and PCI-E with HyperThreading to a Dell Dimension 4600 with DDR RAM and AGP slot without HyperThreading. It's just about the same computer..... Same processor speed @ 2.8GHz...We had two computers, but the other was my Dad's computer and we had planned on just switching computers, but the 4700 also used SATA hard drives and we still had PATA or IDE hard drives...so I kept the 4700 for a bit before trading. But no matter, it's done now...
