Its the original one from dell so i guess thats single pipe. I'm not a serious overclocker at all but when I first got the thing using the old flashing bios overclocking method i got 8171 in 3dmark05 (again, I am sure it can do better). I have since dropped it back to stock clocks to keep it cool.
Here's the 3dmark score if you're interested: http://service.futuremark.com/compare?3dm05=2100158
Perhaps form a baseline specification of the generic i9300 you're interested in, and the average amount of cash you're willing to part with. Obviously, if systems had more or less in the way of specifications, the amount would be adjusted accordingly.
I have a 9300 with a 1.86 PM l 1.5gb 533 l 80 Gb 5400 rpm l 6800 Ultra l XGA + 1440 X 900 l DVDRW Drive l You can keep the bluetooth I would have no need for it. Pretty sure the BT for the 1705 is the same as 9300. System Has no scratches or marks looks 9 of 10. System has 365 days left warranty NDB as of today. How much cash?
