nateman_doo you mean TAPS? drill bits drill holes, taps thread the holes to make machine screws go in the holes you drilled. 6-32 is the universal computer thread tap/screw. next size down is 4-40 (cdrom/hard drive thread size) I would get the following sizes taps: 8-32 6-32 4-40 Can't hurt to have these sizes laying around. If you go to any huge hardware store you could buy a tap & die set, which will usually come with tap & die as small as 6-32, but not 4-40. Like everything, I get it from McMaster Carr.
Q56_Monster I thought I'd run one to see how the 980x works with physx-on. Not too shabby...again low gpu clocks, but I can get over P46k with ease.
