skulltrail is dual cpu for xeons. x48 supports both ddr2 and ddr3 and is just cherry picked high binned x38 boards. Honestly you are wasting money getting a qx6800, since it only overclocks maybe 100mhz more than a GOOD q6600 like mine.
im definitely not upgrading my cpu for a LONG time.. cpus lifetime last a very long time in the gaming world. Im more concerned about keeping my gpu upgraded more.
When i finish everything up i will post up pics for you guys to see my system everything is prob gonna be done by the end of Feb if the GX2 comes out next month that is
I mean you got a 8800gts and q6600 what cant you play? If i were you i would put ur money in the bank and wait until you actually need to upgrade. But if your rich, or just really badly want to upgrade now.. go ahead.
