during last SITEX, acer had a quad core desktop for $799 if i remembered rightly.
i wont recommend you to overclock or spend so much, since you're only a light user.
a heavy user would be using rendering programmes, heavy and intense graphics/cpu usage or a hardcore gamer ( im midcore
)
i overclock my cpu, graphics to achieve better results.
also, in the long run, overclocking kills your computer. a slow death. i have more CPUs than motherboards. in all i've about 4 spare CPUs and 10 dead motherboards, 6dead rams, 5 burnt PSU and more than 10 hdd. with only 4 dead graphics .
like hwat sammy said, not all cpus can overclock.
you might get the same CPU model , samae motherboard and rams but it wont clock the same.
the CPU batch, RAM chipsets and motherboards will differ.
anyone remembered the AMD athlon xp era ? the famouse 1700+ Athlon XP ?
or the barton 2500+ ? lolz for amd fans..
different batch different results
