I'm trying to decide whether I should buy a pre-owned desktop with stats shown below for £300 ($484), or just make a new PC from Scan for a bit more money? The specs for the pre-owned are: Intel 2 Quad-core at 2.40GHz - over-clocked to 3.60GHz RAM: 4GB (DDR2) 250 GB HDD ATI Graphics Card (worth about £60): Total: 2048 MB Dedicated memory: 1024 MB + cheap PSU, old motherboard and a small case The PC is about 4 years old. So it it worth the cost? Or is it better to just start making a future-proof PC?
