My new INTEL Xeon-cpu ( 1240.v2) does not have integrated graphics. It's fast as the i7s , but $60 cheaper and runs on a mid-price MSI-z77a-gd55. I make-do with a "legacy" gt_9400 and 11 yo Viewsonic 19" monitor gawd bless that creature it bleeds no more light now than it did in 2001 !
I've used Linux since SUSE_7.3 and RedHat_6 ... switched to Ubuntu when my **beloved** WinME stopped being rock-solid 4-hours at a time ... so 6.06, 8.08, Now, I run v_10.04 on my production gtx-9800+/MSI-gd70/ AMD_965 ..... and v_12.04.1 on the new hardware. I keep around an old Celeron with XP to run science data-logging HW/SW from DATAQ. Linux is supported ... if you write your own drivers; haha in my innocent youth I did such foolishness.
