[QUOTE="iancalderban, post: 392730, member: 85629"] just to inform my conclusion on this one. I stuck with the 4850e cpu and I got one of [url=http://www.scan.co.uk/Products/512MB-Sapphire-HD4550-PCI-E-20-(x16)-1800MHz-GDDR3-GPU-600MHz-80-Cores-DVI-D-Sub-S-Video]these[/url] , passive and low profile 4550 cards. and all I had to do (from my Integrated graphics configuration) was physically insert the 4550 , reboot a couple of times, then configure CCC. Same drivers (catalyst 8.12) worked without reinstall. Deinterlace with Vector adaptive is automatically enabled , no registry tweaking required. 1080i material is now working very nicely indeed, with VA deinterlace, PQ is much improved. Total changeover time 10 minutes. only fiddle is the overscan/ pixel-mapping behaviour is different on this 4550 card.
