What about your CPU % when only mining with multiples GPU (for Litecoin as an example)?

Is your computer also usable for daily uses (not games indeed!)?

Although CPU is idle but you still can't use your computer freely unless you stop 1 of your graphic card...

For scrypt mining cpu is actually not used much but ram is important, must be 4+ or 4 Gb.

I've 2 x R9 280x on a i5 and 8gb ram, cpu usage only 5 -10%, memory usage is `20%

Sempron 145 with 5x 280x cards, an identical rig with 5x 290 cards, and CPU on both is ~15-20%. I thought it'd be lower than that, but doesn't seem to slow the actual hashing down too much. I'm guessing cuz it's a slow-ass single core?

Edit: Each rig has a single 8GB stick in it.

not much cpu is used, for example i use my fx6300 mine on 4 cores while leaving 2 cores for the system and cgminer to run
anything above 15 on the intensity will cause a bit of jitter

Although little CPU is used it can still make using the PC cumbersome but it seems to be motherboard and card specific. I have one that mines scrypt but I have to keep the intensity of the primary video card down to 13 to stop stuttering occurring when moving a window about. Another that has no problem until the I gets to 18.

Yes. scrypt does not use much cpu at all.
