Depending on the MB you choose - I'm using an Intel DH55HC - you might not even get access to the built-in graphics chip. It requires certain chipsets and then certain connection on the MB and not all Core i5 MB's that accept the i5-661 have it. I'm sure you know that already but maybe the info is helpful for others later. The DH55HC has been a pretty good MB over the last 4-5 months that I've been running the machine and the graphics are OK. They were not so good 5 months ago but the driver has gotten noticeably better. > >> The i5-661 cores are actually the fastest cores I have, and I've also >> got an i7-920 and an i7-980x.

However there are things to learn about machine configuration at this level. The disk systems start operating differently when you have a lot of memory. I'm running 24GB of DRAM on that machine and this effects the way the kernel looks at write back to disk and what not. No problems, just new things to learn. >> This machine has 3 old hard drives in it as well as 2 sound cards and >> a 1394 card and along with the two LCD monitors it still draws only >> about 150W so I'm pretty happy with the cost of running it day to day. >> >> I've not used it at all for Myth since I moved mostly to DirecTV but I >> suspect it wouldn't do badly assuming there's no issues with the Intel >> Graphics driver.

One down side to running Gentoo is that you cannot do much of anything like that without considerable study before hand... > What I would like to speed up is updating various VMs, I have quite some > linuxes in VMs, some of them gentoo-based, and running "emerge -avuDN > world" on them could always need some speedup ;-) > For the price it's been a good purchase I think. I've run Windows XP and Win 7 in vmware and the speed is pretty close to identical on the apps I use. (Mostly TradeStation) I won't do live stock trading in Win 7 under Gentoo yet but maybe one of these days. It's been very stable but for safety most of the time when I'm trading I just run Win 7 native. > Thanks, Stefan You are welcome! Cheers, Mark
