Now an old low end computer is a 2.0GHz+ Athlon 64 system with 512MB + of ram. You see those older Athlon 64 systems selling for less then $100 all the time.
I think one thing is the ever changing definition of an old low-end computer. 4-5 years ago, something low end and old would be a 1GHz P3 - 1.8GHz P4, or an old AMD Athlon. Now an old low end computer is a 2.0GHz+ Athlon 64 system with 512MB + of ram. You see those older Athlon 64 systems selling for less then $100 all the time.
hi worker and PP, sorry i forgot to mention, i'm pretty sure i have put in 768MB of RAM in total to the PC (should have mentioned that) but can't check right now as i'm not at home.
I'd say the ever-changing definition of a low-end computer is towards computers with 'slow', but efficient cpus (Atom 1.6Ghz on eee pcs) and a gig or more of ram?
