Ok, so I decided to overclock the CPU and GPU a bit on my laptop. Used Nvida Control Panel to overclock bit by bit and Prime95 and AtiTool/Furmark to test stability.
CPU : T4400
2.2Ghz stock, Max temps on prime95 around 65 degrees
2.65Ghz overclocked, Max temps on prime95 around 68 degrees
GPU: Nvidia Geforce GT 320M
500/750/1100 stock, Max temps on Furmark and AtiTool around 68 degrees
680/950/1440 overclocked, Max temps on Furmark and AtiTool around 73 degrees
That was a huge overclock, especially on the GPU but the temps remain quite cool. Just wondering if this is normal regarding the temps. I didn't fiddle with voltage settings. Gaming performance improved significantly. Dragon Age and Mass Effect 1/2 are smooth at max details, whereas before the overclock I was using medium graphics and textures. The CPU is the bottleneck in those games as both cores get maxed out to 100%.
