Surveyor is just trying to help you out and keep you on the forum fella. He was replying to mrrad1951 for the most part. We can't link to competitors as that is the forum rules but we will help anyone with any system when asked
You really, really don't want to be using the Bulldozer CPU. If you give us a budget and what you need (OS, monitor etc) we can post some spec's. I guarantee you won't see any bulldozer builds bud. Don't worry about the old machine, if these guys make a living off it and couldn't suss it that's not really your problem.
I have a legit Win 7 Ultimate 64 key and I use a dual monitors BenQ. I will inwardly digest the advice about the Bulldozer and put that out of my mind now..thanks for that. It looked good specs though http://www.overclockers.co.uk/showproduct.php?prodid=FS-182-OE&groupid=43&catid=2040&subcat=1270 and I've just realised its a bit more as I forgot about VAT, I can still do that...just have to be frugal for a month.
