Everyone should own a decent PC if you're gaming anyway, there are plenty of games out there that run much better on PC, Bethesda games being a prime example since they're always so buggy you have to make use of the console to fix yourself!

Of course if you just need a PC for FFXI you really don't need anything spectacular, look at this for instance: http://www.ebay.co.uk/itm/FAST-DELL-...item20f385666c

Not a spectacular PC by any means but will run FFXI effortlessly and only £88.
