like any windows platform you get problems from time to time. anyone spending that money on a pc should know that already. its not a problem for an enthusiast, worst case scenario you just do a windows re-install. you lose a bit of time but nothing major. i had 10 months hassle free super fast computing. recent problem was fixed with a windows re-install.
for a professional i think its best to go for apple but then again you have to be prepared to spend a lot more to get a similar spec. so i think there is still a big market for a powerful pc even they do have their problems from time to time.
Im based in Cork city, sosac photography is listed on google maps. I wouldnt consider €70 to be a lot. The CD rom hasnt even been taken out of the box, so you are getting a brand new product for a heavily discounted price.
