lol ok will aim for that then. there are a few different ones our supplier does :
VX6850 1GBD5-DH - VTX 3D HD6850 1GB DDR5 XFIRE 2xDP/HDMI/2xDVI
GV-R685D5-1GD - Gigabyte HD6850 1GB DDR5 DX11 XFIRE 2DVI/HDMI/DPORT
VX6850 1GBD5-DHX - VTX 3D HD6850 1GB DDR5 X EDITION DP/HDMI/2xDVI

is there much difference?

The VTX cards will vent a bit more of the exhaust out of the case than the Gigabyte card.

However,the Gigabyte has a better cooler and is better built AFAIK.

and the difference between the DH and DHX will be the same as the HD5770 and HD5770 OC, minimal?
