An 8 year old PC is quite an upgrade from a 12 year old box.  It came with a 3rd generation i5 processor that rates as a pretty solid mid-range processor.  Not sure if the i7 would boost the performance much, it is at the low end of high performance processors.  The hard drive is good at 6 gb/sec.  It did not come with a graphics card.  A good card for gaming would be about $200.  I added a second drive for Linux and bumped the memory up to 32 GB.  This should hold me for some time.  The mouse provided didn't work in the Dell setup screen, the cursor floated to the top of the screen.  It and the keyboard are cheap throw ins.  All in all I am quite happy with my purchase.  On receipt of the PC, one of the memory modules needed to be seated and the boot sequence needed to be changed away from NIC.  An error message displayed on each boot about a media device.
