All in working condition, I took them out of my old rig, to build my new one.
Q6600 never overclocked, so I can't give you any feedback there. eVGA 780i, great motherboard, no issues whatsoever. eVGA 9800 GTX 512mb, was top of the line a few years ago, still runs modern games well (not ultra ofcourse).
Also have 2 x 2gb ocz watercooled heatsink DDR2 9400.
I do not have the boxes/etc anymore, will include output flashing for the motherboard though.
Not really sure on what this stuff goes for nowadays? Any suggestions would be great.
