Well after dropping way too much money on an all-new core 2 duo system.. my ram that came was fubar . Took forever to RMA it but now I've got the new modules and am running an E6300 @ 3GHz with 2GB of PC800 on a P5B Dlx!!
As soon as ATi's Vista drivers support Crossfire, I've got another X1950Pro to throw in there too.
This thing is just SO much faster than my laptop which I was having to use for WEEKS. That little thing just chokes on Vista.. time to re-load XP!
