I got a new computer, and built it today.
The processor I got was advertised and sold by AMD as a dual-core, but with certain motherboards, it is possible to unlock 2 more cores if they aren’t defective. Mine unlocked, so I now have a quad-core “AMD Phenom(tm) II X4 B50 Processor”. 8GiB of ram, 1TB of hard drive, and a 1920×1080 monitor round out the computer.
Now I just need to copy all of the data off my laptop.
