Thanks for your answer, I'll go for that then :] All the little bits I've saved on components (£10 here, £20 there) allowed me to buy a better monitor, so it's worth it I think, and since due to bureaucracy and issues in the finance department I haven't been paid in over 2 months and I also have to pay my rent and eat even a few quid makes a difference right now. It was all supposed to be sorted by now, but still isn't and I'm not sure when the money is coming in, but I need the PC for work too :/ So in a bit of a pickle, but hopefully will be sorted both money- and pc-wise soon.
EDIT: The saving on RAM would be over £60. That is a tiny bit more than "a few quid" too. But anyway, getting worked up about it now because I just spent the last week fighting with the finance department!
