Thanks to all for your input and advise. Despite the strong bias towards the i5, I'm going to go the AMD route as during all my searching, I've found another company that is even cheaper than the one listed above, making it pretty much HALF the price of a comparable i5 setup. I understand that overall, the i5 is the superior chip but to me, it's like saying that a BMW is better than a Ford. True no doubt but the Ford is vastly cheaper and still gets the job done.
Yes, I want to play games but it doesn't have to be extreme, no live twitch feeds for example, so I'm satisfied that for the money, a 6 core AMD FX chip will do fine as I've read many good things about it, on here and on other sites and I can't justify spending twice the cash for a small improvement. Sorry Intel fans, that's real life!
