My 2003 system I built died a while back and money is tight so I purchased a refurbished HP Pavilion from Best Buys website. Not top of the line as I used to build but still far better than the 32-bit AMD Athlon 2500+ Barton chipset system I have had for 9 years. This 64-bit quad core AMD with 8 GB of RAM and Windows 7 should be much faster. Especially with a 1 TB SATA hard drive. Would have loved to have been able to build a Pentium i7 system but I am sure this one I bought will be all I need.
