Ok, been playing Vegas on full whack as well as FEAR : Extraction point.
System specs :
Gigabyte MoBo, AMD SanDiago Core 3700 (2.2ghz), HIS x1950 512mb AGP, Creative Labs Sound Blaster Audigy 4 and 2 gig DDR PC4000
Fear runs at about 60-100 FPS, very nice indeed it's so so much better with all the funky shadows on.
Vegas runs between 40-100 FPS, some areas it does slow down to about 15 but I think thats sloppy level design as it appears when I'm looking in a particular direction and is very occasional.
The ATI benchmark will give me 850-900 FPS, my old Radeon 9600 pro gave me 200, so a massive increase for me there.
I'm downloading 3dMark06 now and will post results for anyone who cares
But what is important is that I'm very happy with the performance and that the RMA went through fine without any problems. The whole thing took 5 days , I sent it Monday, they had it Tuesday, It arrived back on Friday - I can't complain about that level of service really.
Hopefully this will inspire a few of you who are hesitant to send your cards back for fear of getting another duff one to do so - OC.co.uk have been very reasonable for me and I can't imagine any different for you guys... and hey.. if any of you live in Lancashire I may drive over and lend you the old 9600 in your downtime
Thanks for the help given to me since I registered, from what I've seen this is a very friendly and helpful forum - I may stick around
