I've had it for about 3 months using a radeon 6670 which isn't exactly a brilliant card! Also, about overclocking the fx 4100, what's the highest you can oc the 4100 on the stock fan? Thanks for the help.
On the stock cooler, I wouldn't OC it any further than 4.2 (which is what a 4170 is clocked at, so the stock cooler should be able to handle that, at least). It's not ideal, but it'll probably do.
I would really suggest an aftermarket cooler if you want to OC much past your current OC, though.
