Is my overclcoking right and how are my temps

[Kaizion]

First time overclocking anything so I was a little unsure on what to do.

Found a short guide on how to overclock my new 1055T so followed that but would like some feedback on what I did and my temps.

Here's my setup:

AMD Phenom II X6 1055T @ 3.5Ghz
CoolerMaster 212+ Cpu heatsink
Gigabyte GA-890GPA-UD3H AMD 890GX
G.Skill RipJaw 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz
OcUK Zeus Tower Case
ATI Sapphire HD4850 512mb X 2 in crossfire setup

Now the way I overclocked was to raise the FSB and lower the HT and NB multipliers along with the Memory multiplier so they didn't go over their operating limits.

The short guide is here:

I played starcraft 2 for 2 hours today and the temps are as follows in the screenie:

They were around 55C, they had dropped a little when I took the screenshot.

Now I know my case is rubbish but I have installed the maximum amount of fans I can on it. I will be upgrading to a coolermaster storm scout at the end of the month.

So simple questions really:
Did I overclock correctly?
Are my temps ok?
Will they go any higher if I play for longer periods of time?

Best thing to do imo is d/l prime 95/linx and run them and see what your max load temps are while the stress test is running. This will also see if your o/c is stable for more then 1 game
