ha, you put a honking video card on that itty bitty mobo... 55w is very good, does the NVIDIA card throttle when idle?
Yep. If the video card didn't, there's no way it'll use just 55W idle. Haven't really put it through my usual battery of tests (Furmark, IBT, etc), though. I don't think the GTS 450 is honking. For the games I play, it's actually much
slower compared to a GTS 250. However, I'm somewhat uncomfortable powering both a Lynnfield+GTS 250 on just a 300W PSU (Silverstone Sugo SG-05) so I went with the GTS 450 instead. The HD 5750 or HD 5770 would have been better alternatives speed and power-wise but I've never been able to fix the silent stream bug (HDMI) on my other cards so I opted for NVIDIA to avoid the issue. Besides, I do use some apps that require CUDA.
I do have another slated build using almost the same hardware except with an upgrade to an i7-860, GTX 460 1GB and ST45SF 450W. The i7-860 and GTX 460 are currently in use elsewhere but I'll be transplanting them to another SG-05B when I find time.
