Ah we've had quite the differing experiences. Yeah the 4100 is poor, every bulldozer CPU was pants in my opinion (no offense to anyone who owns one obviously). In terms of pricing the 8320 is around
£107.99 while the cheapest i5 I can find (i5-3330) is
£125.99. That is i3 money for around i5 performance.
Now before people start calling me a fan boy, In terms of experience with intel I've actually had it good. Currently I own an i7-950 (£60 used, best budget cpu of all time

, still need to get the mobo for it), an i3-550 (best i3s ever made, imo),core 2 duo (old laptop) and a i7-3537U (new laptop). I will also probably soon own another i7 due to me needing to record alot for tf2 matches (video render times on my 8 core is quite slow and I am lazy

).
I also probably mention that I've never had a good experience with Nvidia (poor excuses for drivers, poor cooling and poor build quality, admittedly that was evga's fault though.)and it has left a bad taste in my mouth because of it. I believe that I got my first AMD 'card (my 7870) at a good time, because I've had no driver issues to date and apart from one issue with cooling (thanks xfx) it has been faultless.
To sum this up, experience shapes all of our opinions. My experience with AMD has surprised me in terms of performance (I wasn't expecting much tbh however I get good performance in everything I play) and I'd like them to catch up to intel enough to cause intel to stop being so damn expensive. However your experience with AMD has been a hell hole so I understand why you don't like their products.
also back on topic, the cooler looks like something that you'd fit to a 7750, not a high end card.
